3D model description

I wanted a "big" 20 sided die, so I laser cut some (20) sides and printed 3D corner fittings (12).

This is "adjustable" - bigger faces makes a bigger die. Smaller makes a smaller die.

I originally had "Edge Ties" to glue to the internal edges, but it's way faster to just chop a little bit of a board or dowel rod than to print 30 edges.

I did use the printed ties on the last face since they were easier to glue to the opening, then glue the face in later.

As an option, the last face can be mounted with magnet fittings, in which case you have a door and can use the die as a box!

Additional stuff needed:
* Wood for faces (or another material)
* Dowels for edges (optional)
* 6 10mm magnets (for removable face)
* Construction Glue
* Masking/Painter's tape
* Paint
* Numbers

Full disclosure: Gearbest gave me the CR-10 that I printed this with, so I feel sort of obligated to put it through it's paces.
