Glass Spacer for Monoprice Mini Delta

This is a basic spacer that will hold a 120mm x 3mm glass build surface securely to the factory bed.

The spacer keeps the glass from shifting during prints without the need for adhesives or other "tricks".

FAQ

What 3D printers will this work with?

As the title says, this is ONLY meant for the Monoprice Mini Delta printer. No guarantees will be made for any other printer.
If you have a different version of the printer with different tolerances, let me know so I can update the model!

What beds will this work with?

This is only meant to be used with the factory bed that comes with the MP Mini Delta.

What glass build surfaces can I use?

As long as the glass has a diameter of 120mm and is 3mm thick, this should work for you!
If you want to find one, just search Amazon (or your preferred store) for a "120mm Borosilicate Glass Plate" they usually run ~$10 USD.

Won't the print head hit the top of the spacer?

The top of the spacer clears the print head during calibration, so no.

Does the lip on the model reduce printable area?

The lip is smaller than the printable area of the printer. It takes up 2mm.

Will the spacer affect the self-calibration?

The fit should be tight, but vertical movement should not be affected.

Why doesn't this hold onto the underside of the bed?

I wanted to be able to quickly lift the glass surface without fussing with the spacers. By not holding onto the underside of the bed, the glass lifts right out and is super easy to put back in.
