Transformer Wire Winder

thingiverse

Over the years I have accumulated many wall socket voltage transformers that can easily be repurposed. The problem with them is they get tangled in a box. A Transformer Wire Winder keeps them untangled and prevents damage to the wire. This makes it much nicer to put them in your suitcase when you travel. The arrow on the face of the winder is something I couldn't resist. In my opinion, winding the wire always in the same direction helps preserve the wire. I also like the face. If you don't want to see the face, don't make a color change at the third layer during printing. This Winder has a plug side and a blank side that need to be epoxy glued together. The two sides are made easy to glue with three indexing pins. Splitting the winder into two parts avoided printing with supports. The 110-volt connector is designed like a wall socket, with an internal gradual pinch that grabs the pins. I recommend printing at a 0.2-layer height. PLA or PETG works fine. If you want to be super organized, color-code your transformers - use red for 5 volts, black for 12 volts, and let your imagination run wild.
