Decided to add a glass plate to the heatbed, but the limit switch was too low. Crafted this adapter that matches the thickness of the glass I used (from a cheap picture frame). Re-uses the existing screw of the Z-axes motor mount/bearing assembly. Slot on the piece allows for fine tuning if needed.
If your glass is thicker, use your favorite design program to add the appropriate layer below the z-stop contact arm.
Print instructions
Category: 3D Printer Parts Print Settings
Printer: JG Aurora A3
Rafts: No
Supports: No
Resolution: Normal quality - 0.1mm
Infill: 25%
Notes:
Nothing really special required for this print. I wanted it strong enough to support itself from the one screw, but didn't need to go solid infill. 25% was sufficient.
How I Designed This
In TinkerCAD:
I used basic blocks to design this, and then used an existing model of the Z-motor mount as a giant "hole" to subtract any of the overlapping pieces, rendering a near exact fit. The screw hole didn't line up on my beta print, so I added a slot instead and it worked perfect.
