MK8 Extruder Rep2 Mod Rev 2
thingiverse
Revamping my MK8 Extruder Rep2 Mod, I enhanced the ball bearing placement and wire spring configuration slightly. Optimal results were obtained with two wire springs, although there's room for three. I've included .step source files for your customization pleasure. For this project, you will require a 623 bearing (3mmx10mmx4mm), a 10mm M3 grub screw, a shortened 20mm M3 flat head screw to 18mm, a further shortened 10mm M3 flat head screw to 8mm, and 2-3 wire springs from foldback clips (I used 20mm ALCO foldback clips). A sharp knife, rasps, manual skills, and patience are also essential. Print with Makerware settings of two shells at 100% infill at 0.15mm layers for the best results. Enjoy!
