Wired Vacuum Pump Button Holder

This attachment makes operating your wired vacuum pump for filament storage bags far more convenient. On this type of pump, the power button sits in the middle of the cord, requiring two hands to use—or forcing you to switch it on first, operate the pump, then turn it off afterward. Not the end of the world, but definitely not ideal. This slip-on holder relocates the cord-mounted button to the side of the pump, allowing true one-handed operation. It’s designed to fit tightly over the pump body, and printing it in TPU allows just enough stretch for a secure, grippy fit.
