Xtool Z Axis Height Adjuster

Xtool Z Axis Height Adjuster to fine tune the xtool laser. I have tested on the 10w and 20w laser heads but Im guessing it will work with the other laser heads as well. Thumb screws accept 3mm screws. Also you'll have to drill out the top and middle holes 3mm to bolt the rear part to the z axis main body. I used two 10mm screws for the bottom and middle holes and a 14mm for the top hole. The two thumb screws are 16mm x 3mm and 30mm x 3mm. https://www.amazon.com/gp/product/B0B9MLKSY1/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&th=1
