I created this model to hold the hook up wire that I use in prototyping circuit boards. It is designed to hang on the bin rails we have on our work benches. The parts are designed to print without supports. The rear of the holder has a space to put a 10mm x 2mm magnet to help with holding. The wire guide has a little post that can be used to wrap the wire around it to prevent it from sliding back out of the hole. The parts all slide together with a little friction.
The author marked this model as their own original creation.
