Thanks. That guide is very helpful.
My test at 1/8" walls finished, and things didn’t really get that much better. I also got today a copy of an earlier version of the design from Shapeways - with the 1/16" walls.
Now, I don’t suppose I can expect a printer in my garage to do as good a job as they do, but I’m not sure I’m getting the results I ought to.
What I’m trying to get done is a roughly 6" x 2 1/2" x 2" box - it’s a GPS Clock. The design is open - an earlier revision is on Thingiverse: https://www.thingiverse.com/thing:3895904
Jumping ahead to a reply that came in while I was starting this reply… I not only have very little plastic modeling experience, I’m fairly new to 3D design entirely, and the first thing I did was buy a Form 3. My own little joke is, “Congratulations! Here’s your 3D learner’s permit.” “Thanks. I’ll have that Ferrari over there.”
I took some pictures. First, the Shapeways box. There’s a little bit of a mismatch in the fit, but I am fairly sure that’s because I have friction-fit a piece of acrylic in the front (the design has four stiles to hold the acrylic in place and the intent is to secure it with some glue) that’s a wee bit tight.
The next pictures are out of the Form 3. These pieces were run through the Form Wash and Form Cure with recommended cycles and then were removed from their supports.
