Customizable Spool Hub Adapter

thingiverse

I am using 25.4mm/1 inch tubes to hold my filament spools. I obtained some spools with 53mm/2 inch inner diameter. With this hub adapter, they fit perfectly. There are some filament spool hub adapters available, but I was unable to find one that could simply plug into the filament spool with the correct size. So, I designed a Universal Spool Hub Adapter for the Customizer. You can change the dimensions not only do you can define or remove the collar or chamfer if you prefer. There is automatically a 1mm backlash added to the inner diameter to make it easy rotating on the axle/tube (Advanced Settings). On the outer diameter, there's also an extra mm added to fit it tight on the spool (I called it "Arm Compression" in the Customizer). I uploaded the 25.4mm version for the original Prusa i3 HEPHESTOS holder. Many thanks are due to Runkel for creating and testing it. After seeing fcartegnie's clever parametrized remix, I added three new versions of the 25.4mm adapter with only four arms. There seems to be a rendering problem inside the Customizer, which I couldn't find out. However, the resulting STL files are perfect.
