Multiple Mechanism Auto-Rewind Spool Holder, Adapted for Prusa 2kg Spools

I have been using these very reliable spoolholders by ea69 for a few years now and always wanted to have one for 2kg Prusa spools. I used the step file and made the stand and the threaded shaft 40 mm wider. I did not know the parameters for the thread, so I just cut the shaft a bit from the end on the gears side and extended it by 40 mm. Threads will hardly be required in the extended portion of the shaft. I also added some fillets to the many sharp corners to make the model a bit more pleasing to the eye and perhaps reduce stress points on the model. I have included the Fusion 360 project file with my mod as well as a step export of that project. I have added just the two parts I modified here, please use the rest of the parts from ea69's original model.

Stand and Threaded Shaft were extended by 40 mm to be able to handle Prusa 2kg spools. I added fillets to the sharp corners.
