Titan Extruder Carriage X Sensorless homing

This is my verion of X-carriage for titan extruder + IR sensor from filastruder.com. This design is meant for X sensorless homig (hence the square extrusion on left side). I added IR sensor mounting but it's a bit long since my hotend is longer becuase of longer heatbreak - you may customize this. You need to glue part cooling fan duct or print it in ABS and use acetone.

For assembly, you will need:

7x M3x18mm + 7x M3 nuts for x carriage
2x M3x40mm for extruder mounting to x carriage
1x
