Y Gantry fo 20mm Extrusion (Core XY)

thingiverse

Designing and building my own CoreXY printer. I'm only using 3 printed parts this is one of them its designed to fit 20x20mm extrusion and hold it as a y axis. you will want to m5 tap the 20x20mm extrusion no adjustment, eccentric spacers or messing about is needed for use with the mini gantry wheels, just 4x m5 25mm bolts 4x m5 standard hex nuts 4x m5 washers 4x mini V wheels 8x m5 lock nuts it is important to use lock nuts! as the inner diameter of the locking part of the nut is the perfect size to not lock up the mini wheels! put one either end of the wheel the locking part towards the wheel! (so the last lock nut is backwards) Drill out the 4 holes with a 5mm drill bit to make sure the bolts fit through without being held by the plastic, the nuts on the rear are used to hold the bold straight and in place, if you screw the bolt through the plastic (which is very easy) it is very probable that it will be at a slight angle! (you don't want that)
