Adjustable Z Endstop

I read mixed this Z endstop bracket for my Geeetech A20M, the original design is great it just needed a little help I didn’t like how all the screws just went into the plastic and that the whole thing was just held up by a small pen spring I’m not sure how or if this even worked and if it did if it was reliable so I added some M3 size nuts where all the screws go, I added a set screw in the side for after you get it set you can lock it in, I also added a couple of different bracket offsets since my printer has reinforcing brackets on the side I can only use the holes on the brackets so I made a couple of different sizes along with the original with no offset. Everything fits together pretty tight so you will need to do a little sanding to get it all moving smooth. I hope this helps you out it has been working great for me. Happy printing
