easy keychain

cults3d

I used a pen spring to create an easy keychain, allowing you to remove a key very simply from the keychain. Everything is printed in PLA at 0.1mm with a speed of 55mm/s, except for the fasteners which are printed in 0.2mm at 10mm/s. To ensure proper cooling between layers, several fasteners need to be placed on the tray, typically three or four.
