3D Printed Battery Cradle
« on: April 04, 2015, 01:44:42 AM »
There are some special batteries, called 18700, that are actually longer versions of the 18650 Li-Ion batteries.
In my flashlight hobby I use such a battery cradle to test-power electronics, but long enough cradles are far and between.

I had the chance to take a 2-lesson 3D printing seminar.
So a long enough 3D printed battery cradle was my first project.



standard 18650 with printed adapter


leather rivet and spring contacts


3D printing IS one of the ways of the future

I've wanted to try my hand at 3-d printing, just never pulled the trigger to do it, too many irons in the fire as it is :)

That really is cool.  I'm looking forward to when these things will be as common as ink-jet printers.

I really like the copper rivet contacts. I'm going to steal that idea.

THIS^^^^^^^^^  It's getting here quick.  We were just discussing here on the forum the other day that some public libraries have 3D printer labs now.  It's just a matter of time.

Cool.  My local library has them available for residents to use.  I'm giving it a try soon.

Be my Guest....the particular ones are not copper, but some kind of plated iron.
But they have a good form and also allow soldering.
this is also a minimal contact resistance option, cos the battery really touches tined thick wire, a departure from any battery carrier outhere.

They are to get a nit outdated soon. Soon there will be in the market a new printer that uses a different method that will be 10 as fast. There is a pool of material on a vessel with a UV transparent bottom. Material is spot by spot hardened solidied by a UV beam, and item si raised upside down.
That means we gonna have 3D printer srvices in the photocopier shops in,say, one and a half year?

BTW, I consider myself conservative when i say that Tinkercad (the online drawing software) can be used by starting high-schoolers.
