Yet another spool holder

thingiverse

Just whipped together a hack to enable feeding my printer from an auxiliary Robox spool not connected to the printer. Utilizing some ~10mm plastic tubing I had lying around, I fashioned it into connectors for assembling the holder and used it also as an axle that passes through the spool. The updated middle path on this design features a mechanism with teeth to secure the reel in place. This way, I can reuse the setup to wind different filaments onto a Robox SmartReel using a drill. Version 3 allows manual winching of filament onto the spool by providing a slot for it. Version 4 boasts a square hole extending throughout the adapter. In order to accommodate this feature, I included a crank arm and corresponding components in the package. A round axle and Robox adapter are highly recommended unless you intend to use a crank arm. I added an enhanced version of the holder that accommodates bigger 1kg spools as well. Additionally, spool adapters have been optimized for 3DPrima, Colorfabb, and Taulman spools, although they're not strictly necessary since the central core of these reels already includes a round hole. These wider reels necessitate wider holder and axle constructions to ensure smooth usage if you plan to switch between different types of reels. Printing Details: The hack was created with a PLA material and an infill density ranging from 15-20%. A standard four-layer configuration (two layers at the top, two at the bottom) was utilized along with three perimeter layers.
