Many of the z-axis I was looking for seemed a little to big and expensive or either to "Chensy". I decided to design and build my own. Turned out really nice and works perfect. I designed this to directly mount on my OpenBuild carriage and 6watt OptLaser.
The parts used for mounting on the gantry and laser are split into 2 pieces. Did this so you can rotate the mount one way or another to get somewhat of a customizable height. Once you have it they way you like it then just glue the pieces together.
All of my stuff is generally a work in progress no matter how long I've been tinkering. Even on this project I can't decide on keeping it so you glue the pieces or adding holes for set screws. Please let me know your thoughts and I can update the drawings. Even if you have a different mounting layout I'm ok with drawing up a custom part if needed. I added some pics, stl's, skp's in the files tab.
Update: Here's a video of my Acro System with the ZAxis moving to "Home" position. Also installed all my flexible cable channel and end stops.
