JG Aurara A3 Z Limit switch for glass plate

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.
