Welcome to the party @marc.simon1!! All those links look awesome.
To add on to the 123D Catch software, I just recently learned about Autodek’s Momento, another software that generates 3D digital models from photographs. I’ve heard really good things about it, it’s free, and it will output really high definition meshes!
www.onshape.com is a fully cloud-based 3D parametric CAD program that runs on browsers (Mac, Linux, or PC), smartphones, and tablets. It’s free with all features, but limited on private storage (free public storage), and has numerous 3rd-party add-ons, a few of which look pretty handy for Glowforging.
I have a quick question for you all…the table I plan to set up my Glowforge (shipping soon) is 24 x 37". Is the inch overhang going to be an issue for me? I plan to vent out of an adjacent double sash window when in use…can folks share how they may have similarly set up a temporary vent hookup? I have a historic house so I do not want a permanent mount to the outside. Thinking of a setup that can be installed much like a window air-conditioner where the sash comes down to hold the vent in place.
Nope. The feet (which are really rails running the length of the GF) are inset quite a bit from the outside edge. There are posts with the exact measurements.
For your venting, it’s easy enough. A piece of wood, acrylic or even foam insulation board with a 4" hole in it that you can mount a dryer vent through is all you need. You can paint the outside to match the house so it’s less obtrusive. The dryer vent usually has a plastic piece that covers the pipe and has flaps to keep things from coming in when the exhaust isn’t blowing. You attach the vent hose from the GF to the inside of the dryer vent piping. About $10 at Home Depot.
When you want to use it, raise the sash, slip in the piece of wood/whatever and drop the sash down to hold it in place. You can put a strip of weatherstripping to help seal it from smells. Also, you’d want a strip of weatherstripping you can put in the gap where the upper & lower sashes meet so you don’t get backflow of exhaust air coming back in through the gap.
Lots of folks doing something similar. Plenty of posts to see how creative people are here
