Cable through fitting for 220V 2 wire Euro cable (8mm hole)

thingiverse

This tiny piece can be slid onto most standard Euro cables to prevent damage when routing the cable through hard surfaces, especially metal. Just drill an 8mm hole, slide the fitting over the cable, clip it into place and secure it with some hot glue. If your project requires adjustments to this design, simply modify it in a 3D modeling tool like Tinkercad!
