**Fusion 360 files are included** 3018 CNC Short Limit Mount - Print 3 3018 CNC Long Limit Mount - Print 1 (used on the X axis side with the lovejoy) I printed them on their side using a raft and supports! 2h49m 25% infill PLA The hardware used to secure them was included, along with a stainless steel nut and bolt to mount the limit switches. A stainless steel nut and bolt were not strictly necessary, but my local hardware store only had that small size in stainless. It cost about 6 bucks - I consider this highway robbery! Credit https://blog.shahada.abubakar.net/post/adding-end-stops-limit-switches-to-the-3018-woodpecker-cnc-router Due to slight variations in the machines being sold, the design allowed for some adjustments. However, in my opinion, they were a bit weak, especially considering one of the mounts is located front and center on the machine and prone to bumping. Please feel free to edit and distribute this as you see fit. I have not yet resolved the Z-axis issue but I am using the 500w spindle. When I get it sorted out, I will include it here. I intend to make a universal version for both modified spindle mounts and OEM units! Unfortunately, I have not found an existing version of the Z-axis that meets my requirements because I am uncomfortable with using super glue to secure the switches.

Personally, I just heated up a nail and pushed it through where I wanted the holes. X-Y will also work with this type of limit switch. https://www.amazon.com/gp/product/B01I1E84SG/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1 I prefer wheels when possible, but they are not necessary. Recommendations I recommend printing the file named "Limit Switch Mounts Pair" and test fitting it to your machine to see if any changes need to be made to the included Fusion 360 files.
