Adjustable Z end stop - Wanhao i3 Plus (Small switch)

thingiverse

You'll need to modify the smaller Z-stop switch that came with your Wanhao i3 Plus to fit it properly. To do this, drill small holes in the lower part of the assembly to secure the switch or use hot glue to keep it in place. I had to remove the metal jumper headers from the plastic connector and feed the wires through a hole at the top of the lower part. Then, I reattached the headers to the connector. Upper: Add two bolts - M3 x 10mm as a retainer and M3 x 30mm as the end stop screw. Be careful when cutting threads for the first time you insert them. Lower: Press in two M3 lock nuts. Use M3 x 10mm bolts to secure it to the printer frame.
