Update (20 Oct 2024) – Added **two new frames** – one hanging, one standing - for round hydrometers (42mm opening). Also added **two universal spool holder designs**. One is threaded with angles sides so it can accommodate a range of spool hole sizes and widths. Just screw them together to sandwich the spool between the sides. The other holder is fixed width (70mm) with a deep-set axel that should accommodate any spool with a hole of 50mm or greater. With this design, the spool loosely “rides” on this spool holder. **I prefer the threaded version**, but I thought I'd give you all a couple options. I also adjusted the bearing hole slightly, so it is easier to insert the bearings. **Update (23 Sept 2024)** – Added a 62mm axel option along with 62mm and 72mm “deep” axels with optional spacers to accommodate narrow filament spools. Multiple spacers can be added to fit any width spool. **Update (22 Sept 2024)** – Fixed an error in the 60mm axel CAD models that caused them to print a
