3mm Prusa mk2 remake

thingiverse

All parts I make to build my own Prusa will be uploaded here. I entered the world of 3D printing at i2mendel, so I have many 3mm filaments left over. This extruder can eat both 1.75 and 3 mm filaments. If you want to use my parts, you'll need suitable metal parts from China, of course. The main thing you'll be needing is the E3Dv6 that can eat 3mm (and a teflon tube to use 1.75mm). You'll also need bigger NEMA17 motors and drive gears as seen in the photos. The quick-exchange Y_idler for bearing pulley with axle 3mm is also required. The pulley can have teeth or no teeth, and it measures 8.5 mm wide by 9.6 mm diameter (without teeth). It's a complementary part to the drive pulley T2 with 20 teeth, as seen in the photos. The extruder idler uses a 685 bearing. I recommend printing the extruder with ABS, and the Y_idler with PETG, using a layer height of 0.2-0.25 mm. Supports are optional if you want them. I use this motor bracket: https://www.thingiverse.com/thing:1914857
