Here’s my quick journey into shot glass engraving. I created this to help my daughter engrave some shot glasses for her and her graduating suite mates at college:
I also used his 950/100 at 225lpi settings to engrave - AND - his super clever tip about a thin film of dish soap to get better results. I had 100% success on the engraves.
The jig is designed for use with these square shot glasses I found on Amazon. They look good and are pretty cheap. Most importantly they provide a nice broad surface to engrave on.
I choose to create the jig out of 3mm MDF that I have laying around. This material is a bit thinner than the proofgrade MDF, but I I designed the jig so it shouldn’t matter. I’m lucky enough to have snapmarks enabled so I used those as well
Here’s the final Jig:
Lastly after an engrave session:
And finally the SVG - Make sure you assemble with with the bottom/middle/top in the correct position since each panel is slightly different to put the glass at the correct angle, hold it in position, but still allow insertion and removal from the top. The side panels have a score in the center to help align the center layer.
Hopefully this is useful to someone!
@jules - FYI - this was the jig I was having the problem with, but it worked like a champ today.
v1.2 of the zip has ben updated to break out files by layer to simplify usage. The original layered file is still included ‘- All Layers.svg’ in case some of you would rather work with the layered orignal.
Hopefully this makes it easier to use for everyone!
