Monoprice Maker Select IIIP Y Pulley Block Support

thingiverse

This is for a monoprice maker select but would most likely work with a wanhao I3 plus too. This gives support to the metallic block that is only held by 2 screws to the frame -- so that it does not slightly twist inwards as the y axis belt is tensioned. You will need to change the existing bolt (can't remember if it was an M3 or M4). The bolt that came with the printer will no longer be long enough. I believe I used a 20mm long bolt to replace the existing one. update 6/4/2018: I decided to completely replace the metal block. So this new support version now houses the pulley and is also attached to the gantry through M3 nut and bolt. So the original M3 that holds the metal block needs to be replaced with a longer (preferably 12mm) bolt. I also noticed that the metal block is about 2mm higher than the stepper motor on the other side of the belt. So this entire support block is now 2mm lower.
