[SML] 3-D printers

[Dale Farmer]

Low budget.   Sheet of plexiglass or plastic, clear/colorless, the size 
of your finish opening plus half an inch or so on each edge for 
mounting.   Drill holes around the half inch edge for screwing to the 
scenery.

Get a couple tubes of clear colorless bathroom caulking compound and a 
tube of grey or white.     Gloves and a helper with clean hands would be 
advisable for the next steps.   layout on the plexiglass the block 
pattern and the mortar spaces between them.    Prepare a set of forms 
from scrap luan or masonite the size of the glass blocks.  Put the forms 
down and use them to guide to lay down the seams between the blocks with 
the white or grey compound.  Let the compound cure overnight.

the next morning, use razor blades and scrapers to correct any mistakes 
in the 'mortar'.   Now use the clear colorless compound to coat the 
glass block areas and use spatulas and pieces of scrap wood to sculpt 
the layer of compound on the window to look like the glass surface. 
Place the thing outside to cure, unless you love the smell of acetic acid.
