Auto-rewinder stand for Rubbermaid 16 cup container

thingiverse

It appears that you've provided a detailed text on how to assemble and modify an auto-rewind spool holder for 3D printing. Here's a summarized version with headings: **Assembly Instructions** 1. **Retaining Ring**: Place the retaining ring (washer with a break) over the shaft until it snaps into the indentation. 2. **Axle+Spring**: Insert the axle into the spring stack so that the flat-sided hole is against the retaining ring. 3. **Rewinder Hub**: Push a 608 bearing into the end of the hub shell and into the threaded end cap. 4. **Hub Assembly**: Assemble the hub in the spool by inserting the spacer, shell, axle+spring, and end cap. 5. **Final Assembly**: Place the container over the lid stand, press it down, and feed the filament through the feed tube. **Auto Rewind Spool Holder Modifications** The original design had issues with 90mm wide spools, so modifications were made to accommodate a wider spool. * **Spring Modification**: Reduce the number of spring blades from 9 to 3 (PETG) or 5 (PLA). * **Axle Design**: Create an axle with a retaining ring to hold the spring in place. * **OpenSCAD Changes**: Fix coplanar-surface bugs and add comments starting with "//am" to indicate changes. **Rubbermaid Container Rim Profile** The lip of the container is composed of three arcs: 32mm, 300mm, and 2250mm. A function was created in OpenSCAD to generate a polygon representing the outer rim profile of the container's lip. This is used to construct the spool stand.
