This is a tray that can be used to hold hand chalk. Ir can be used stand alone or as a part of a wood holder. There are STL files for two variations, with slightly difference base diameters and center post heights. The OpenSCAD file is also provided.
There is a hole down the center than can be used to screw down onto a shelf or custom holder.
You can order the chalk on Amazon, or get at your local billiard supply store.

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!
