Update (6/24/2019): Added new versions of the z lead screw holder. They were made from modifying the .step files from BLV in Solidworks, so they are no longer janky af. Also added an experimental z endstop mount (first version did not work, adding two alternatives).
Update (5/29/2019): Added v2 of the Z motor mount. This moves the endstop forward, meaning it should be more in line with the whole thing. Should make the trigger piece irrelevant, as well as allowing for a small circular trigger and overall desired performance. I have printed the part but not tested yet. And yes, it is a disgusting mess after being ripped apart and stitched together poorly in 3D Builder. 8)
Update (5/24/2019): Added endstop trigger. Everything works as intended. Not as well as I hoped, as the trigger needs to be angled a certain way, and the original design is a bit too loose for my liking. But it works. Maybe next I will look into making a circular trigger that will not depend on alignment. WIP progress removed.
So I really suck at CAD.
I designed a Z endstop mount that works similar to BLV's original intent, but with the RAMPS style endstop. Turns out, someone else has made on that allows for fine adjustment, similar to the one I had on my original AM8... But they designed it for use with a longer 2020 extrusion on the x axis. So I slapped two designs together in an aggressively ugly fashion. Here is the result. I tried to clean it up in SolidWorks, but it just yelled at my incompetence.
Microsoft 3D Builder allowed me to smash the two files together easily, but damn is it ugly. I also remixed the motor mount, no clue if it will fit. I hope! I reversed the face of the switch mount, then moved it inward a bit more. You will also need to print a wheel like in that guy's pics. I'll be trying out thing:1404339
This design is untested, I'm hoping it will function exactly the same as the original.
