Never lose count again from FidelioScorpio on Thingiverse:

Remix to separate the pieces for easier printing.
Merged the inner piece into the bottom as it didn’t need to be separate and aided glueing.
Also rounded the number holes for improved aesthetics.

I’ve printed 3 of these. I printed the top, bottom and cogs in 3 separate prints each time. The first counter was solid colour with a paint marker pen to colour around the numbers. The next 2 (pictured) were printed with changing filament just before the layer that put the backing on the numbers. If you’ve got the time and inclination, this came out very well & I highly recommend this method.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
