Remix of Hart's Cube Puzzle (https://www.thingiverse.com/thing:2132796)

When playing with it the corners were a bit too pointy, so I added an option to chamfer the corner points

Modifications :

- Added chamfer to corners

- Added a gap value of 0.5 : When printing with a voron the gap of 1mm was too loose.

Model in picture was printed with the following settings :

- 30mm size

- 0.12mm layer height

- 0.5 gap

- 2mm corner chamfer
