Robo 3D 1+ Filiment Spring clip

thingiverse

This clip is a vital tool for effortless filament changes on my RoBo 1+. With only one arm, it's absolutely essential to have something that can securely hold the printer open without requiring me to remove the screws every time. To use it effectively, simply hook it over the tap, pull it back, and position the lip over the screws to keep the "mouth" of the printer open for easy filament removal and insertion.
