This part relocates the cr-touch probe so there is no longer a y-offset between nozzle and probe. Zero y-offset means no movement of the bed during probing, which should result in a more precise mesh. This will only work if you've already modded your hotend cooling as this part is incompatible with the stock setup. The cooling shroud I use has been designed by "Nathan Builds Robots", for a detailed howto, watch his video "the silence of the fans". Should be printed with a heat resistant filament, PETG; PCTG, ABS, ASA or the like. I used PCTG and followed CNC kitchen's recommendations on how to increase part strength by printing transparent. See https://www.youtube.com/watch?v=9qb25Gi4Jv0 If your horizontal expansion isn't 100% dialed in, (mine isn't) I'd recommend using drill bits to clean up the holes after printing, so the screws fit. Sizes are 2mm(2x, top), 2.5mm(2x, probe), 3.5mm(2x, extruder motor), and 4mm(1x, bottom). If you're of the "clumsy persuasion", maybe cover up the now exposed electrical contacts with tape. Initially, I had designed it like the original part, with a cavity for the outsticking backside of the connector, but that made supports neccessary for print and I figured that there shouldn't be any metal parts near the extruder while the printer is running, so I just removed the top. On my machine, the new probe offsets are: x-offset: -33,9 y-offset: 0,0 z-offset: -2,63 (always start with 0,0 and fine tune using the paper method!) Your offsets might differ slightly, especially 'Z'! I've printed this for the second time now and after cleanup, it fit without any issues. I'd be veryinterested in your feedback on how it worked out for you.
