This is a small and portable abacus for your children! Designed for easy printing and a sturdy build, the Posts are printed separatedly and assembled to prevent them from breaking at the layer lines. Print 10 chips for each post and a cap to prevent the chips from falling out while being transported.
BUILD TIPS: Just press the post into the base by the narrow side of the post. You will usuallyt need 10 chips for each post. The tolerances on the post are meant to make it hard to remove, but i would suggest printing a single post first to make sure the fit is just right. Increase Flow by 5% if the posts is too loose, or falls off easily, and decrease flow by 5% if the post doesnt fit in.

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!
