Ender 3 Toolhead for Sherpa Micro, MGN12C and CR Touch

QUICK UPDATE - I measured the original X-axis endstop mount, and it is much shallower than the one I am running, but I believe it may be too shallow to clear the linear rail and trigger on the carriage.  I shaved down the one I am using by about 2mm, and it now clears the fan and CRtouch mount, and does trigger with the carriage, so I was able to eliminate my endstop trigger, and my X-min is now 15mm outside the bounds of the bed surface, which is perfect for my use case.  I also have been tinkering with a slightly different 5015 mount setup so that the bolts will clear the Sherpa Micro.  I may post those once they are less ugly, but since I may switch to the Klicky probe soon, I might just wait to post another remix until I have that sorted.

I wanted to find a toolhead design to use my new Phaetus Rapido hotend, and decided to give this one a try.

Original model was for the MGN12H rail carriage, and my machine had the C, so I remixed the mounting holes to fit.  Changed the BLtouch mount to fit the CRtouch I already had, and changed up the extruder mount holes to suit the Sherpa Micro I had already printed and assembled.

Everything worked great, except for the ABL mount, which impacts the X-axis endstop/pulley cover I have (somehow I have completely forgotten where I got that model, and have managed to delete the STL, but it looks like a basic cover).  I have not tested it with the stock Ender cover yet, and did not get a chance to measure the one I have against it to see if going back to the stock cover would fix the issue.  I was admittedly too lazy to switch them out, or adjust the mount location to fix the issue, so I made a little trigger that mounts using the rear CRtouch bolt.  Hits the endstop with about 2mm to spare.  This moves my X-axis home location about 6mm inboard of the bed perimeter, which may or may not be a deal breaker for you.  I will probably address the issues in the next few days.  At this point, I've already crawled into the rabbit hole.  Might as well see it through to the end lol

I am thinking of trying out a Euclid, or Klicky probe soon, so I may add a variation for that in the near future, as well as possibly adding the ability to run a Switchwire style drag chain setup, and I may add accomodations for some kind of LED lighting to make it easier to see my nozzle.

Props to Ofek256 for the original design.  Well thought out, lightweight, yet rigid platform.  Moving from the Biqu H2 Revo w/ the M.A.D. system using 3 Noctua fans and CRtouch to this brought me down from well over 400 grams to under 280.  For another comparison, just the printed parts for the Voron Stealthburner weigh in around 275 grams before adding any fans, hotend, extruder gears, ABL, or electronics.
