TronXY X1 makerbot z end stop bracket

thingiverse

This bracket allows you to use MakerBot's limit switch on the z-axis. Most brackets available are press-fit, which I dislike, so this one lets you attach screws from the back (it has holes for countersinking) and secure it firmly in place. The original bolts will work or any other M2 bolts of the right length. If a bracket is attached to the rear of the PCB, through-hole switches will be present, causing spikes in the back - that's why there's an indent, and the same applies to the connector when it suddenly stops. In theory, this should work with any 2020 extrusion printer. It works well; I would change one thing: I'd make the part extending forward to the other side thicker so it doesn't twist and can be mounted lower. I ended up sanding it slightly. If you're interested in why: The print quality in the picture is poor because I was repairing the printer from being kicked around for over a year, held together with duct tape long enough to print replacement parts. It's good now; I might reprint later. I shattered the original z-axis limit bracket years ago when I bought the machine, which lacked holes for countersinking screws and I made the mistake of trying to create them using a drill. I broke two of the original limit switches and two cheap replacements (I still have about 20 of them). I got tired of the original and replacement limit switches breaking so I'm switching to MakerBot's ones, which I bought a long time ago when I was going to build a bigger printer. https://www.thingiverse.com/thing:4090771
