X Gantry Plate for 20mm extrusion

thingiverse

Designing and building my own CoreXY printer from scratch. I'm using just three printed parts for this build, and one of them is a critical component that makes use of M3 heat-inserted threaded inserts. This design eliminates any need for adjustment or fuss when pairing it with the mini gantry wheels - all you'll need are 4x M5 25mm bolts, 4x M5 standard hex nuts, 4x washers, and 4x mini V wheels. Don't forget to use lock nuts; their inner diameter is perfectly sized to avoid locking up the mini wheels. Install one lock nut on either end of the wheel, with the locking part facing towards the wheel (so the last lock nut is reversed). Drill out the four holes using a 5mm drill bit to ensure the bolts fit snugly through without getting stuck in the plastic. The nuts at the rear are used to keep the bolt straight and in place - if you screw it through the plastic, it's likely to end up at an angle (which is something you definitely don't want). There are 12mm square holes for attaching a 10mm GT2 belt; simply loop it around and secure with a zip tie. This design also includes a standard 30mm spacing adapter, commonly found on Prusa-type printers. If you need to mount existing Bowden or extruder mounts, this will come in handy. The hole spacings are carefully designed: 15mm from the center left and right (or X-axis) and 26mm up and down (Y-axis). For those interested in the print settings I used for this build, here they are: * Printer Brand: Prusa * Printer Model: Prusa Steel * Supports: Doesn't Matter * Resolution: 0.18 * Infill: 20%
