square key
thingiverse
I designed three square keys in various sizes. With the name of my dad prominently displayed on each one. I printed these keys out using PLA without any support material, with four to five outer layers and a 30% infill density. The dimensions of the keys are as follows: 7.8mm by 7.8mm, 8.4mm by 8.4mm, and 8.7mm by 8.7mm.
