Description

These little covers are notorious for breaking and/or getting lost, so I created a 3D file. The one in the photo was printed on an FDM printer in ABS, and the thin legs broke off after removing it. I think PETG or a more flexible material would be better and last longer. Printing on an SLA or DLP printer in a strong resin would be ideal.
