One of the clips on my Father-in-Law's outside electrical outlet cover broke so I designed this replacement in Tinkercad.
I printed at 0.2mm 100% infill using PLA+ and it's not broken after several months. Probably best to be printed in PETG for strength and flexibility or perhaps stronger just to be use though.
The title image is the original clip (because I forgot to take a photo of the new one before installed it!)
