Tray-hung spool holder

thingiverse

A custom filament spool holder is designed to neatly slide into an existing aluminum extrusion attached directly to the wall within a whiteboard tray. The model's design requires attention to its structural integrity, as it can be prone to flexing and may not provide sufficient support for heavy loads. To mitigate this issue, users are advised to secure the spool rod with self-locking nuts or consider upgrading the holder by printing thicker parallel parts and adding a stiffer support bar. For those interested in modifying or customizing the design, Fusion 360 files are available upon request.
