Based on the mathematical packing problem: how can you fit a certain amount of unit squares into the smallest possible rectangle? Read more about the packing problem of x squares on https://www.combinatorics.org/files/Surveys/ds7/ds7v5-2009/ds7-2009.html

Details

• 17 keys in the optimal packing solution for 17 squares, with options to opt for 2u vertical or horizontal keys in the bottom corners
• MX-compatible, solder only
• Diodeless
• Pro Micro footprint
• Silicone bumper feet cutout on the bottom
• 0° typing angle
• Features the 40%s community Logo where this project originated from
• The Case was designed and optimized for CNC milling, but is also 3D printable. A CNC'd case has not been prototyped before
• If interest persist a small Groupbuy may be held eventually
