Reddit reviews Redrex Right Hand 1.75mm Filament MK8 Bowden Extruder Frame Block for Reprap 3D Printer Kossel Mendal Prusa

Honestly this, https://www.amazon.com/gp/product/B01LO3HKK4. The $2 part that broke basically made it impossible to print. If I knew that would happen I would have gotten this from the get go so that never happens again.

Its teflon tube so glue isnt gonna stick to it. I tried. you need a M6 bowden connector and a M6 nut. Print this part https://www.thingiverse.com/thing:2793080 by removing the 2 screws holding the bowden connector down and removing it. Hold the tube in place for the duration of the print with your thumb. It will suck but you can do it, i believe in you. This part will let you attach a regular threaded bowden connector to the new MP select mini v2 with the modified cheap ass bowden fitting. Once that's in place, even only halfway screwed in print the base of this part. https://www.thingiverse.com/thing:2756509 you don't need the arms, just the base. Once that's printed remove your extruder feeder, screw in the new base, using the M6 nut attach the threaded bowden conenctor. Put the old arm on, old screw, etc. You're good to go. How do I know this? Oh no reason. I just did it a few days ago...https://imgur.com/a/SOCXXzn


Or RMA your printer and wait 3 weeks for a new one...your choice. A pair of M6 nuts cost me like $0.49 at the hardware store and 10 bowden connectors was like $8 on amazon. I also tried this "bolt on replacement" and it didn't fit correctly. https://www.amazon.com/Redrex-1-75mm-Filament-Extruder-Printer/dp/B01LO3HKK4/ref=as_li_ss_tl?ie=UTF8&linkCode=sl1&tag=mpsmwiki-20&linkId=da5703adf10e92d89680d3fe34074fc3

Since they're not a standard version, they are a bit trickier to find. You could always upgrade to something better that uses something more common - https://www.amazon.com/dp/B01LO3HKK4/ref=cm_sw_em_r_mt_dp_U_ifWTDbNDDR30Z
