CoreXY Ender3 Style Hotend Mount
thingiverse
I'm excited to repurpose an Ender 3 MK8 extruder to experiment with a dual Bowden setup and came up with this X axis carriage, which I thought might be helpful to others. The belt tensioner caps used are the original ones from the CoreXY frame design: https://www.thingiverse.com/thing:2138286. Additionally, I've included printable extruder spacers that you can print or use 4.5mm of washers to achieve the correct spacing for the extruder mount. The bolt pattern on the carriage is specifically designed for a MGN12C linear rail block.
