Glass bed for Snapmaker


For those interested. This is how I added a glass bed.

  1. Bought a 128x128 mm 4.7 mm glass sheet

  2. Design and printed a spacer for between the z-axis and the x-axis (find attached STL)
    _z_mount.stl (26.8 KB)

  3. Designed and printed (using carbon filament ) clips for holding the glass (find attached STL)
    clip-8mm_v2.stl (8.5 KB)

  4. Moved the x-axis axis (arm that holds the print head) up one hole using the spacer and washers to secure the top part of the x-axis (see pictures)

  5. Home axis - I checked that there is enough space to place the glass on the bed - the print head module should not touch the glass

  6. Placed the glass on heated bed - secure with clips

  7. Calibrated the bed carefully - as to much pressure on glass will certainly break / shatter it

The clips works for now but need to find a better way to hold the glass in place

You can probably use a binder clip to hold the glass in place. A medium one would work with the thickness, just take off the arms once you’ve clipped the glass to the bed.


Thanks for your sharing.

I’m curious how does the glass bed perform compare to the original sheet?
The one shown in the picture looks good, but have you tried any taller and bigger stuff?


Adhesion to the original bed has slowly deteriorated, so much so that i only got good prints when using blue tape. (Printing with carbon fiber directly on the bed did not help) The blue tape stick so well to the original bed that it was always an issue getting the printed part of the bed - main reason i started looking at adding the glass bed.

Certainly just printing on glass without glue-stick or blue tape is difficult - the original bed is much better. However using blue tape on the glass works well and its much easier to remove the printed part.

I ordered some PrintaFix and will test this on the glass.


Sounds nice. I had the same issue with the original bed, but I ended up with a pei sheet.


Just a warning when you use a binder clip or anything that clamps to the heat plate. I ruined my heat plate with a binder clip when it scored the bottom of the heat plate and the copper heat elements were compromised.


Thanks for sharing your experience. This is very useful information for everyone. I guess it’s not a good idea to use binder clips.


i also print 4mm glass, but i built the Z-axis with M5 nuts = 4mm higher. I coat the glass with wood glue (1:3 water) and each print holds super. Whether PLA with 40°C bed temperature or ABS with 80°C, no matter. I fix the glass with double-sided adhesive tape on the aluminium plate.
the perfect solution for me.
