Wanhao Duplicator 6 and Monoprice Maker Ultimate Bowden Conversion

thingiverse

I made this bowden conversion so I could easily use aftermaker extruders afterwards. The one I am using is a Chinese Bondtech BMG clone from Triangle Labs. The extruder motor mount is common amongst their extruders, making it also usable for the Titan, for instance. They even sell the mount separately, I believe. This is what I bought: https://es.aliexpress.com/item/Trianglelab-Bowden-extrusora-BMG-extrusora-clonado-Btech-Dual-extrusora-para-3d-impresora-de-alto-rendimiento-para/32917029058.html?spm=a2g0s.9042311.0.0.293663c0syTViu The pneumatic fitting is an M6 and the hole for it comes in two sizes: 5 mm and 5.5 mm. The 5 mm is the correct size to tap an M6 thread, but I was able to force the fitting into the 5.5 mm with some pliers because my piece was printed in ABS. I recommend printing in ABS or PETG since the plate can get hot, but PLA might be fine too. I have only tried ABS personally. Mounting: To mount the plate itself, you can reuse the same screws found in the corresponding holes from the start. To mount the ribbon, rotate it and use the screws that were originally holding the stepper motor – the long ones. I rotated the ribbon at the back between the last two clips so there is less stress on the ribbon clip. The stepper motor mount is straightforward, but you do need to get some M4 screws and nuts to attach it to the mount. The mount is printed with no tolerance to the hole, making it fit snugly without moving. If it's too thick to go through, you may need to sand it. You will need a longer stepper motor cable for the extruder. You can either buy one or extend it. If you buy one, be sure to pay attention to how the cables are in the pins because if they're positioned differently your motor won't spin. Needless to say, this extruder motor mount isn't compatible with an enclosure.
