Harbor Freight Sand Blaster glass spacer frame

Spacer for glass frame when using 1/4" safety glass with disposable 1/8" glass sheet under it.

My original glass was damaged. 

I found a ¼" thick piece of safety glass locally adding 1/16" of an inch thickness.   Then I decided to switch from the plexi overlay (since I now have the safety glass) and I added an 1/8" blaster side disposable glass… adding another 1/16".

Mine is the 62144 model. 

I broke the print up to be a puzzle so it fits on my print bed.

There are recess holes in if you are using sheet metal nuts.  If the alignment is off a Dremel can adjust.   

It adds 2.6mm to the thickness.. as it assumes the foam compresses down to 1/16" of an inch.

Mine was 646mm wide and 343mm wide (outside dimensions).  This spacer has a brim around the existing frame.  

I suggest printing a corner first and check the fit.

I printed mine in black PETG.
