TronXY X5S Rear Mount BLTouch and X Endstop bracket

thingiverse

Rear mount bracket for the X endstop switch and BLTouch or 3d Touch sensor, designed specifically for the TronXY X5S family of printers and potentially other printers with the same X carriage setup. Inspired by this original design but not a remix: https://www.thingiverse.com/thing:2989393 And also influenced by this thing: https://www.thingiverse.com/thing:2815399 However, since my X carriage is now mounted on a linear rail, I needed to keep things simple and slim - just add some bosses to connect the touch sensor and ensure there's still room between the carriage and frame at Y max. The bosses are sized to allow M3 screws to self-tap. In my setup, I'm using M3x16mm screws. With the screws almost fully inserted into the bosses, my configuration has a -2mm Z offset. A genuine BLTouch comes with small conical springs that can be used to mount it to this bracket with some height adjustment. If you have a "3D Touch" or don't have any springs, most music stores carrying electric guitar parts or having a guitar technician on staff will be able to provide a set of springs for a "single coil" style guitar pickup. They're conical and are literally what's shown in the photos here. I've included a 1mm spacer just in case your springs aren't long enough or you prefer not to use them. Your slicer can scale it in the Z axis to whatever thickness you need. Edit 9/16/2018: v0.2 has been tested and is working great. My offset, as pictured, turns out to be X-12 and Y+57, so this ends up being a wash compared to the mount on the fan duct (which was X-57 Y+12) but at least it looks better to me. Your offsets will likely differ unless you're using the same E3D mount and X linear rail conversion I am. Your Y offset is probably going to be smaller in a stock configuration.
