Improved Spool Holder for the Original Prusa i3 MK2

cults3d

If you own an Original Prusa i3 MK2 like mine, you undoubtedly love it without a doubt! However, (in my honest opinion) the spool holder is quite inadequate - difficult to adjust and set up. As such, I've decided to design my very own which can accommodate any type of spools and switching filament has never been simpler! In the folder that you will download, I have included some typical CAD formats so if you like, you can modify them to suit your needs. If you're interested, feel free to watch this video where I demonstrate how I created it: https://youtu.be/ehwsGeesCF0 (Italian version) P.S.: In the downloadable file, you'll find an FEA Report which allows you to visualize all the stresses and forces acting on the model as well as a PDF with the spool holder's dimensions. UPGRADED VERSION 3.0: I have released an upgrade to this design which is slightly larger in size but optimized for printing at 0.3 mm layer height instead of 0.2 mm, resulting in only a minimal increase in print time. By making it bigger, I was able to significantly reduce the deflection in the arm and by optimizing the dimensions for 0.3 mm layer height, it has become noticeably sturdier than before. P.S.: If you decide to print one, I would be thrilled if you could post a photo of your print on this page. If you encounter any issues, please don't hesitate to write them in the comments and I'll do my best to resolve the problem!
