This is a chalk holder for up to 10 chalks based on the hand of a Lego Minifigure. When you print it in the original size it can hold chalks with a diameter of 10mm. If your chalks had a diameter of e.g. 12mm scale it proportional to the original thing with 1.2 (or e.g. with 0.8 if your chalks had a diameter of 8 mm).
I'm a student who found his fascination for 3D Printing when our school got a 3D Printer. Furthermore I'm interested in modeling things with a CAD software. Have fun while browsing through my things!
If you have special wishes for things I could design, please let me know! :D
