UPDATE 16/02/2024

For anyone wanting to use threaded inserts instead of nuts, I created version 2.0

___________________________________________________________________________________________________________

I liked the idea of swiss key holder, but could not find the one that would fit me, so made it myself. I designed it with only 2 bolts, as the 3rd middle would not allow for correct fit with my keys, but works just fine like this.

Print instructions

• Printed in PLA, but any material should do
• No supports needed
• 3MF and gcode are double color, variable layer height
• 20% infill
• 3 perimeters

Additional hardware needed

• 1x M3 locknut
• 1x M3 screw 10-20mm (depends on number of keys (M3x16 for 8 keys))
