Replacement and Upgrade Parts for Prusa i3 A602

thingiverse

I purchased the Prusa i3 "A602" kit through AliExpress or Ebay, and the majority of printed components are included on the SD card, allowing for seamless printing of replacement parts as needed. Unfortunately, during the assembly process I accidentally broke the X-Endstop-Holder, which was constructed from 2mm acrylic. To rectify this issue, I re-created the part using FreeCAD. Additionally, I encountered problems with the Y-idler mounting block, which was printed in the incorrect orientation by the original manufacturer and began to crack after a short time in service. Since the STL file for this component was not included, I had to redesign it as well. I also developed a replacement spool holder that is compatible with filament spools featuring 75 mm center holes, such as those supplied by 3dfactories.com or made from cardboard, and M8 threaded rods. After printing two of these holders, I mounted them on the rod using M8 nuts for added stability. As always, users are free to modify the included FreeCAD files. **Instructions:** **X-Endstop** 0.2 mm layer height **Y-Idler** 0.2 mm layer height, 50 % infill, printed with support (possible rotation may be necessary).
