Ever need a little clip to control cable sprawl? Don't want to pay a buck a piece? Don't want to wait a month for them to arrive from Communist China? Well here ya go. There are other cable clips on the Thingiverse but I think this one is the simplest, easiest one to print and it works just as well as anything else. But that's not all! It's all parametric, so you can change the size by just plugging in new numbers. And if that's not enough, the source code is included for your modding pleasure.
Print in a semi-flexible plastic like polypropylene. 210 deg. extruder, cold bed, use clear packing tape on the bed to keep the part secured, enable cooling, print fairly slowly (30 m./sec.), 100% infill, no support, no brim, raft, etc.
