X Gantry Plate for 20mm extrusion by zx81

Last crawled date: 3 years, 1 month ago

Designing and building my own CoreXY printer.
I'm only using 3 printed parts this is one of them its designed to use m3 heat inserted Threaded inserts.
no adjustment or messing about is needed for use with the mini gantry wheels, just
4x m5 25mm bolts
4x m5 standard hex nuts
4x washers
4x mini V wheels
8x 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)
there are12mm square holes for use with 10mm GT2 belt nothing fancy just loop it around and use a zip tie
there's also an 30mm spacing adapter which is pretty standard on prusa type printers if you want to mount any existing bowden / extruder mounts.
Hole spacing's are 15mm from the center left and right (or X axis) and 26mm up and down (y axis)
