BLV mgn12 AM8 RAMPS/Makerbot Z endstop & cover

Update (5/14/2019): v4 uploaded and IT WORKS. Now I just need to redesign the cover, as it does not fit. The Solidworks files have not been updated, they have been converted and mutilated several times now. Gross.

Update (5/10/2019): Added a version of the endstop cover with a lil hole to see the LED being triggered. Also added v2 of the endstop mount. This shortens the standoffs slightly, and adds a tapered, slightly thicker end to the screw hole to get better bite/longevity. doesn't fit, but I'll fix that.

Update (5/9/2019): I updated the endstop cover. I added some pretty chamfers and fillets, and optimized the geometry to cover the entire switch. I also thickened the walls and deepened the screw recesses. I think it looks pretty nice :D

I got some replacement RAMPS/Makerbot style endstops and wanted to use them for my Z axis. I found a good remix for the X-axis, but didn't like the Z-axis version. So here is my own. I just used some dimensions found online, so it hasn't been fitted and tested yet. Due to its renovated geometry, it will need supports to print. Included is a cover, not sure if it fits :)

This should mount to any 2020/2040 extrusion really.

Use any resolution or infill you want. Shouldn't matter, as long as it is rigid. How I Designed This

I took BLV's design and chopped off the mounting plate and swapped it for the Makerbot/RAMPS endstop geometry. I designed the cover by using reference geometry found online and added some extra clearance. I then had to mirror the cover in Windows 3D builder because I suck. So if you modify the cover SLDPRT then make sure you mirror it when finished :P
