Laser Height Adjustment for 1/4 inch Bolt

Description

Laser Height Adjustment This is a remix of the height adjuster for the Laser Master 2. I have the 20W laser and decided to design it for a standard bearing and 1/4-20 x 4″ hex head bolt, which was much easier to find.

Laser Height Adjustment I used a narrow washer and nut to secure the bolt to the bearing and a little glue to keep the bearing in the housing. A 2nd 1/4-20 nut gets put in the inner part. I kept the M4 hex head bolt for the locking screw
