c-bot / d-bot multi-purpose x carriage

thingiverse

I'm designing a versatile plate that allows me to easily switch between different tools and accessories, including fans and sensors. My plan is to create multiple parts based on this design. Right now, I'm printing the plate twice and using it for both sides, which might be overkill, but you never know when I'll need more flexibility - maybe even with a quad extruder in the future! To use this plate, I need heat-set inserts, which can be sourced from Lulzbot or McMaster. The inserts are spaced 20mm apart and should fit perfectly into these holes. Lulzbot has a great tutorial on how to install them. Here's what else you'll need: * 4 mini-v wheel kits (delrin or polycarb) * 4 6mm spacers * 4 6mm eccentric spacers * 4 M5 45mm screws * 4 nylock nuts (or regular and thread lock) * 26 heat-set inserts per plate I'm still experimenting with the extruder mounts, but I've noticed that the titan large diameter gear screws can stick out too far, which might cause issues during rapid transitions. Keep in mind that this is a work in progress - I've assembled it and tested movement, but haven't used it for any serious projects yet. Any suggestions or ideas for improvements are welcome! I plan to add a laser engraver mount and eventually try out a CNC mill. The c-bot you see in the photos is a small form factor, which allows me to test and iterate on this design without disrupting my main printer's workflow. The plate might look huge compared to it, but that's just because of its compact size!
