Ender 3 CR-10 X axis linear rail - direct extruder

thingiverse

This is a remix of my own X axis linear rail conversion design specifically for this design by Hangtight: https://www.thingiverse.com/thing:3594559 One of the screws which holds the extruder bracket on has been modified so it now goes through the bracket, through the shroud, and through the new X carriage, locking them all together when it's tightened. This replaces the carriage with a printed one and uses a new system to attach the belts. This conversion requires no drilling. This is designed to use a standard size truck. If anyone wants a carriage to use the larger trucks most Chinese rails use, please comment and I'll upload one for you. The top v-slot wheel mounts are reused to give the belts a strong mounting point. Because the belt now attached above the gantry, you'll need to invert the X direction in firmware or reverse the X stepper motor wires. You'll need a longer belt. I use these to terminate its ends: https://www.thingiverse.com/thing:3746242 The hotend mounting point should be sanded or filed smooth to insure the hotend sits level. If you use the included Y endstop switch mount, you'll only lose 4mm of Y build volume. The rail is attached with slide in t-nuts and M3 screws. You can use this to help align it: https://www.thingiverse.com/thing:2804412
