Slip cases for batteries.(3D printed)

Anyone need some slip top battery carriers? 

I did. 

Well, kinda… This was a drift of another project I did in the last few days, a small cartridge box. Realized the same design could be made to hold just about any cylendrical item… like a battery. SO I remodeled from the ground up to give me a fully parameter-izable model. Now I just plug in numbers and I get different sized cases. 

I Have wanted a safe way to carry a spare 18650 for a while(not that I HAVE a spare but thats besides the point… I have ended up with a loose cell some days and its annoying. )

Anyway. 

battery cases! 

I did 3 basic designs for me, a 4xAA box, a 3xAAA box(headlamps anyone?) and a 2×18650 box(somehow, not shown… hrrm.).  Need to go back and do something for 2 or 3 16340 or CR123, just in case I ever need it. OR wait till I need it… lol. That was the concept to an easy to use pre modeled file.. Print as I need things instead of 2 days of modeling every time. 

These are printed in PETG, a little stronger than the other plastic I have(PLA), with a good heat resistance, and a bonus of being resistant to most chemicals, and waterproof(most soda and water bottles are PET or PETG).

To be geeky; they are printed from a 0.4mm nozzle at a whopping 0.8mm line width(everything says not to go over 150% of nozzle width, which would be 0,6mm… I haven’t had a single issue with 0.8mm. Tempted to try a full 1mm.) in vase mode(Spiralized outer contour in Cura) at 0.25mm layer height, 235C nozzle, 70C bed temps. Filament is Sunlu 1.75mm PETG. All from a Elegoo Neptune 2S.

I’m trying not to totally 3D geek out in these printing posts, but will tell you a little about the mechanics, and the trick I found, for getting these to print in a different style.Normally these would take about 1.5 hours to print top and bottom, and use about a dollars worth of plastic. IN “Vase Mode” they print in 1/3 of that time, and use half the plastic, or less. The thing is, that Vase mode, normally only prints the outermost surface of an item as one continuous line. It compketely ignores the insides no matter what it is, and can’t print any horizontal surfaces beyont to base/bottom. Thanks to a guy on YouTube, I now have a trick. You slightly change the structure, by slitting into the side of the object, connecting the inner and outer surfaces, in essence tricking the software so it prints both. No top surface, and Slight loss of structural integrity(although the clearances could be tightened so that the lines touch and fuse at the ends! ) but for most things the difference is negligable…. UNless its something you plan to run over with a tank… then this might not be a good approach. 😉

Anyone interested in the print files,both STL and the fully parametarized OpenSCAD file to create different boxes, I have it uploaded to my account at printables.   A big bonus, this will make cartridge boxes, just need dimensions of the cartridge in question!

A new way to make plastic parts.

For me anyway!

Something I’ve wanted since they came about, but could never afford or really justify. Until now!

When you come to two new projects, and re-visiting 2 old ones, that you couldn’t finish,and need to sit doen and carve parts from micartan or acrylic blocks…

You just finally buy a damn printer, and be done with it. 😉

:D

one of these
https://www.elegoo.com/products/neptune2s-fdm-printer

is now on its way!

Did a lot of research, watched a ton of videos, got the opinion of a trusted friend thats into printing, etc..


Think I made a good choice for a Non bare bones kit, entry level printer. We shall find out!

Evercraft 150 lum pen light.

One more new light. This was purchased on a whim, it popped up in the checkout area of napa’s website. For $4.99, I figured why not?

Branded Evercraft. Its one mode, 120 lumens. Runs on 3xaaa, which it came with. Given the cost of alkaline batts these days, I think I paid about $1.50 for the light! Lol.

Its all plastic, verry lightweight.

One long bar led?

[​IMG]

I expected the butt end of it to be magnetic like I’ve seen on these bar lights before, so I’m a little disappointed. But it does have a magnet on the clip, and the clip rotates/swings on the light for aiming it, which is kinda nice. Will see how it works in use.

With Jetbeam BC10 for scale.

[​IMG]

It is freaking bright! I’ve no doubt its 150 lum, or at least 100.

Might actually grab a couple more of these things to throw in glove boxes or tool boxes for cheap backup/ emergency work lights. Looks like they’re $10.99 normally, they’re $6 off this month. Even @ $11, I think I’d get at least one, can’t see anything wrong with it.

Fenix E03R(new micro pocket flashlight! )

New toy!

[​IMG]

I picked this as a donor to cut up for a new mod/custom project(details on that soon!), trying not to have to build a light/driver from scratch.

But after I ordered it I realized that its cased in solid aluminum! And would be a real bitch to take apart without hurting the innards.

On top of which, I really started to like the idea of keeping it as is.

Its just arrived, and I must say I won’t be able cannibalize it for parts, I Really do like it!

When they say small, they mean it! I bought it mainly on its external dimensions so I knew where I could fit the parts, but even then I was surprised how small it is!

[​IMG]
[​IMG]

Absolutely amazes me that on high this thing is only 40 lumens shy of the BC10 on high!

Full specs, details of operation etc, coming soon when I do a review after I can get in a few days of carry and use.

USB upgrade thingy.

New little doodad.

[IMG]

Old phone was micro USB.
Got a nifty 64GB thumb drive a few months ago, regular big USB for computer(or in my case, my tablet has a big USB port) on one end, micro on the other.

[IMG]

Before that I had moved my archive of photos off of my phone, and tablet, to micro SD cards. Which are a pain to change, and go through if looking for something. Not to mention easy to lose. Unloaded 4 of those onto half the little drive.

Anyway. The new phone is USB C.

The new doodad is female microUSB to male USB C.

[IMG]

Works great, new phone likes the drive with no transfer issues.

Got two of them, gonna add one to my go-kit, either jacket or bag, in case I need to use an older cord with the phone.

Magnetic USB Charge Cords.

I first saw these last winter sometime, I think around November.

Took me till January to decide “why not?” and try it.

A little background;

I use my phone as my only internet device at home, and e-book reader too. Holding it is fine, but invariably after a while, you end up resting the end of the phone on a surface. The end with the charge port. That about half the day (or longer on a 5 year old device on its 4th battery) has a cord plugged into it… You bend the cord over. A lot. Too much.

Aftera while it breaks the thin wires in the cord.

I was going through about 1 good flexy braided cord every 2 months.

So, I figured a 90deg ended cord was a good idea. But most had the 90deg end aiming the cord left… which meant for the 3 places where I sit(or lay) the most, the cord would still make a bend or loop, 180 deg, to get to where it needs to goe. Not only does that eat up cord length, but its another place that can wear out.

Then I saw these. 90deg. End. 360deg rotation. Fast “plug in” (get the phone within 6″ of the cord end and it jumps to the phone! Great for one handed while driving!!), braided cord cover. LED that shows it has power.

I got a 3 pack. 3 cords, 3 micro usb ends.

And there is the other great feature; You can get Micro usb, Lightning, Usb C tips that go into the phone– and they snap in, staying put.

And use just 1 cord for any and all devices!

Recently with my new phone, I needed a USB C end. Ordered 1 more cord and that tip, which are whats shown here. My other 3 cords are bright red.

Now, I did end up damaging the end on the one cord I use the most, to charge you now have to press the cord into its magnetic tip slightly. Loosened a wire. But it took 3 months to do it!

The set of 3cords (3ft. Each) w/ tips was $16. The single set was $8.

$5 to $8 every 3 months IF I ruin them is plenty cheap enough. Much better than monthly as before!

My only real gripe, and its a minor one, is the LED indicator end. In a dark room, you can read by it! Hell, it does a passable job as a night light in a dark (15’x15′) room! Its just a little annoying as a bed side charge/reading cord.

I’m keeping one cord in the truck, one in the den, and one at the bedside. And currently I use them for 4 devices! An old phone thats media and gps in the truck, another old phone that’s media and internet at home, a tablet, and my EDC phone.

I’m intending to get more of the inserts/tips to do 3 or 4 other items, like Bluetooth speakers, and headphones, etc.

The W Box.

An older project. I started this in the summer of 2018, for a friend’s birthday. His name starts with a W, thus our title above. 🙂

He does electronics work, so when I found this old amp meter, in DC milliamperes, in some stuff that had been my Dads, it seemed perfect for a gift.

But i couldn’t just give a bare gauge…

Ok, I could have, but where’s the fun in that? 😉

I missed the birthday.

And Christmas.

Managed to get it done and give it in the spring of 2019. Ha!

But anyway, here it is. Only the 3rd box I’ve ever built in my life. (So don’t judge me too harsly!)

Its white oak, and curly maple. It was entertaining to get it how I wanted it, rabbeted construction, a place to store the leads (plugs and leads stolen from an old multi meter I took apart), but still compact. Engineered and re-engineered seveeal times, but I got it!

I don’t really have all of the pics I could, no step by step.And no steps of progress like I’d like… Hust a mishmash of what I managed to take, and the final product.

Dmax Armor S5 Active screen protector.

So, time for a new one.
This one fits great; much better than the last. Instead of holes to go around speaker, buttons etc, it’s C or U cutouts around them. It’s thicker, but still slightly recessed inside the “lip” around the phone screen. And much to my surprise and delight, it has a much better glare protection; I can almost use it in full sunlight!
All for another $6 shipped!
It was extremely well packed, a hard box, alcohol wipe, drying wipe, a dust collector pad, stickers to use for locating it, and then tucked in with the screen itself, a micro fiber cloth! Screen itself was in a thin plastic sheet bag, inside a padded bag.

If it’s half as durable as it is well packed andaccessorized, it should last at least the next 3years!
I’ll have to dig around and see if I can find another camera, a way to take a pic of it on my phone, and post it. Even as boring as that might be to see, it’s still weird to post about it and not actually be able to show it…
