3 Wheel X-Axis Gantry for 2020 V-Slot Extrusion

thingiverse

I'm creating a new printer using only the extrusions I have on-hand from 2020 and 2060. No need for me to purchase anything when I have a stash of materials just waiting to be used. This modular carriage, designed by MSA (https://www.thingiverse.com/thing:1839201), really caught my eye. To complete the build, you'll also need to download and install the rest of the spacers and top wheel mount from the original Thing that I remixed this from. I've used a similar design on a previous build, but since I'm working with 2020 and 2060 rail for this project, I had to modify MSA's original design to make it fit. This is the version I came up with specifically for the 2020 X-axis. The printer was built using ABS plastic on my Up! Box+. One thing to watch out for: this carriage is designed to use 24mm wheels, and if you try to use anything smaller, you won't be able to tension the wheels properly in the V-slot. Some of my own wheels were only 23mm, and they wouldn't work at all.
