MBX (Mono-Block X) Carriage for BLTouch - Bowden - HEVO

Last crawled date: 4 years, 2 months ago

This is an original design I came up with to try and simplify the creation of the X carriage for HEVO/Hypercube setups. The holes on the back of the mono-block are intended to be tapped with 4mm screws. I'll be surprised if anyone ever uses the set screw provisions, given the tolerances of the bearing bores. Here's a few quick specs:
Bearing bores are 19mm ID, designed to work with 10mm ID rod bearings
slots on the side are for the belts to pass through and be retained by 4mm bolts/cap screws
-- No interface between the screw and the belt should be needed, as the screw tip is 2/3 the surface area of the belt width
The extra 4mm hole provisions on the extruder mount side are hold-overs from the piece-meal design I originally had. Use them for wire clips or whatever you want.
The BLTouch mount works without a nut (if you are so bold), but otherwise you should have plenty of space for cap screw and nut to retain it
The mount is Bowden type, and is designed to be used with brass inserts.
The blower mount at the top of the carriage is also designed to be used with a brass insert. You may need to increase the bore size just a bit by filing. YMMV.
Good luck, let me know if there's any improvements you'd like to see.
I also sell an all-aluminum X carriage block (minus extruder mount) for $55 + shipping. Message me if you're interested.
