Summary

A customizable spacer for the monoprice mini allowing you to print a spacer that clicks onto the z block. This allows you to add any glass thickness to your bed and effectively move your z zero point up to match.

A particularly nice benefit of this style of spacer is that it allows you to insert and remove the spacer without disassembling the machine at all.

Also nice that it prints with no overhangs and no supports at all.

Print Settings

Printer:

Rafts:

Supports:

Doesn't Matter

Resolution:

0.2mm

Infill:

100% or walls only


Notes:

Normally you can set up the wall widths of your slicer to force the slicer to only generate walls to print this. In Cura especially take a look at the layer view and make sure it did not leave the spacer hollow. If it does make it hollow simply reduce your wall thickness to 0.4mm and increase infill to 100% to force a proper fill.

Post-Printing

Installing version WITH levers (no disassembly)

Before anything else, turn on the printer and move the z-axis up a distance greater than the Extra Height you've chosen so that the spacer arm will fit. For example if you're using 1/8" glass you'll want to move the z axis up 4 mm or so.

From the rear of the machine slip the hook side of the spacer through the gap in the tower and click the spacer in place on the side of the z axis block as in the video. Gently tug on the levers to make sure the hooks have clicked in, and use the lever to adjust them if not. A chopstick from the front cover hole can be helpful if you have trouble.

Installing version WITHOUT levers (requires disassembly)

IF you've chosen the spacer without the levers you'll need to disassemble the mini as follows:
Remove the bottom cover of the mini to expose the bottom tower cover screws. Remove the rear white tower cover of the mini by removing the tower screws on the bottom and top. You can also remove the front if you wish, it makes it slightly easier to insert the spacer.

Now just click the spacer in by hand as in the video. Make sure the hooks click over the bottom and top.

Printing one now. Went to Home Depot and got a 10inx8inx3/32in glass pane and a $5 glass cutter. Printing a 2mm spacer and cutting the pain to 130mmx130mm. Thanks!

Did the 2mm spacer work with the 3/32in thick glass? Looking to do the same but want to make sure I print the right thing!\

Thanks

Yes, its slightly less than the thickness of the glass but there's plenty of adjustment in the bed screws to compensate for this. I printed this and installed it once and never thought about it again.

very very nice! Thanks also for videos! :)

Glad you liked it! As soon as I printed mine, I wished immediately that I'd designed it earlier.
