Remix of Spannerhands spool system

thingiverse

This is my take on the ingenious and practical Spannerhands spool system. Parts are carefully curated from various sources, modified by myself or newly designed to fit perfectly together. Two groundbreaking features have been added: * detachable gelbox (no need to pour gel beads into or out of the cassette) * filament guide inside the PTFE coupler (filament doesn't get stuck when inserted) Apart from printed parts, you'll need: 2 x 608 bearings (id 8 mm od 22 mm) for smooth operation 12 x 10 mm M3 screws + nuts (locknuts advisable for added security) 1 x fitting for PTFE tube (with R1/8 male thread) for precise alignment 1 x PTFE tube for effortless movement 1 x 4.7cm x 2.7cm x 1.3cm hygrometer to monitor moisture levels No supports are required unless explicitly suggested. Print the following in PLA for optimal results: 1 x base (print with 10 mm brim for added stability) 1 x lid (10 mm brim for secure sealing) 1 x hinge (can be printed horizontally without supports for convenience) 1 x hinge nut 2 x 608 bearing mount 1 x core 1 x ptfe coupler If you need a wall mount, choose between: 1 x wall mount (screwed directly to the wall for added security) or 1 x 20x20 T slot mount (attached with sliding nuts to a profile for easy installation) For some reason, I printed the following in orange PETG (considering thickness of perimeters and top + bottom): 1 x ptfe coupler 2 x clasp bracket The seal should be printed in very flexible material (92 ShA or less) with <= 10% infill: 1 x flex seal The clasp, on the other hand, should be printed in a material with 98 ShA and 80% infill: 1 x semi flex clasp Finally, I've modified the base to have a replaceable silica gel container which you need to print in PETG to withstand drying in a fruit and mushroom dryer without deformation. It's recommended to print it in clear PETG if you use silica gel with an indicator color so that you can easily see the state of your gel. The gel box should be printed with the perforated side oriented downwards: 1 x gelbox2 (change orientation and use supports) 1 x gelbox2-lid As an alternative to the core, consider using an auto-rewinding core for added convenience.
