About this 3D model

This nifty guy likes to keep your filament from rolling off the shelf! I designed it to fit my shelf, but with some ingenuity I bet you can make it fit yours too. There's three main pieces: left end, right end, and middle. No hardware required! The pieces click satisfyingly together like puzzle pieces. The slope is designed to match the curve of your filament spool to stop it right in its tracks.
