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

thingiverse

The main idea behind this plate is to allow me flexibility in what tool I put on the x-carriage, where I put fans and other sensors etc. I'm planning to create a few parts which are based on this plate. At present I'm just printing this plate twice and using for both sides. Technically over-kill but you never know ( quad extruder anyone? ) To use this plate you will need heat-set inserts. Either from [Lulzbot](https://www.lulzbot.com/store/parts/heat-set-insert-tapered-m3-05mm-internal-thread-38mm-l-x20) or [McMaster](https://www.mcmaster.com/#94180a331/=1b6shc7). I have set the spacing to be 20mm center to center and they should be just the right size to take these inserts. The lulzbot guys did a nice [write-up](https://www.lulzbot.com/learn/tutorials/heat-set-inserts-tips-and-tricks) demonstrating how to put them in. You will also need the following: 1. 4 x [mini-v wheel kits](http://openbuildspartstore.com/xtreme-mini-v-wheel-kit/) ( either delrin or polycarb ) 1. 4 x [6mm spacers](http://openbuildspartstore.com/aluminum-spacers/) 1. 4 x [6mm eccentric spacers](http://openbuildspartstore.com/eccentric-spacer/) 1. 4 x [M5 45mm](http://openbuildspartstore.com/low-profile-screws-m5/) 1. 4 nylock nuts ( or regular and thread lock ) 1. For each plate, 26 heat-set inserts ( see above for link options ) I'm still messing around with the extruder mounts. The titan large diameter gear screws around with the spacing so it sticks out kinda far which could make the hotend subject to moving during rapid transitions. Also note, this is a work in progress. I've assembled it and done movement tests but have not used it for anything serious. Any thoughts or ideas on improvements or changes would be welcome. I plan to make a laser engraver mount and going to try a cnc mill later. The c-bot you see in the photos is a small form factor so I can iterate on this kind of stuff without taking my main printer down so the plate looks huge ;)
