3D Solutech Masterspool - post release design

thingiverse

This is an updated design for 3D Solutech Masterspool filament. 3D Solutech is a US-based filament manufacturer that's starting to offer Masterspool filaments. This design is specifically tailored for 3D Solutech Masterspool filament, which features a cardboard core with the following dimensions: Masterspool Filament Core Diameter: 75mm Masterspool Filament Thickness: 67mm Masterspool Maximum Outside Diameter: 195mm (can print without issues on a 200x200 print bed) I've incorporated design ideas from @RichRap3D Masterspool v4, allowing users to zip-tie loaded filament for partial use. This enables you to print one Masterspool that can be used with multiple filaments. Filament Loading: 1) Place the Masterspool filament over the Masterspool hub, aligning the zip ties into the slots in the hub. 2) Mate the Masterspool end onto the Masterspool hub and screw together until the zip ties cause the Masterspool end to bind or stop. 3) Cut off the zip-ties from the Masterspool filament. 4) Tighten the Masterspool end to the hub the remainder of the way. Do not over tighten, as this may break the Masterspool. 5) Insert the free filament end into one of the slots in the outer edge when not printing. Filament Unloading: 1) Slightly loosen the Masterspool end from the hub until the zip tie slots are aligned between both ends and the hub. 2) Insert three zip ties or Velcro straps through the end of the Masterspool and between the Masterspool hub and the cardboard tube the filament is wound on. 3) Route the zip tie or Velcro around the outer edge of the filament and secure the spooled filament. 4) Remove the Masterspool end from the hub. 5) Remove the tied Masterspool filament from the hub and store. November 3, 2018 - The design of the hub part was updated to match a newly created version with 608 bearings directly in the hub and end: https://www.thingiverse.com/thing:3193164 November 2, 2018 - A 608 bearing spindle for this Masterspool was created: https://www.thingiverse.com/thing:3192173 November 1, 2018 - The "end" part was printed and interfaced with the "hub." Loading and unloading instructions were added. November 1, 2018 - The hub print is complete, and the spool hub is below the cardboard insert (see photo) as designed. The end part is printing and expected to take up the gap difference. October 31, 2018 - Physical models of this master spool are currently being printed. These parts should work based on dimensions. My R&D prints of the threaded ends printed well and screwed together perfectly. When both halves are fully tightened, the slots may not light up to zip the filament; simply loosen slightly, insert zip ties, and secure before removing the end piece from the hub piece.
