- Shaved the bottom by 0.25mm to make a flatter surface
- Retained original holes, but added 4x2mm magnet holes on both
This design lets you 3M double sided tape mount the top piece to the underside of a table and then stack them under each other with 4-4x2mm magnet. I mean I guess you could put them on top of the desk too if you wanted and stack upwards.
I originally printed it with 4.4x2.4 holes. The 2.4 depth fits perfectly, but the 4.4 diameter was a bit loose. I readjusted it to a 4.3mm diameter to make it a tighter fit, but haven't printed it so it's untested how snug the magnet is! I originally wanted to use 6x3 magnets, but 3mm is too thick and there isn't enough material
