Now that the hinges on the Fidget Cube are smaller (see yesterday’s post), we can make the cube itself smaller. Let’s start by going down from cube length 20mm to…
After more testing we figured out how small we can make the hinges on the Fidget Cube and still have it print reliably in one piece. (The answer: 1.5mm radius.)…
Today we finished our customizable print-in-place fidget cube model. By changing just a few parameters in OpenSCAD code, we can decide whether the fidget cube will have a snub configuration…
On Day 142 we printed a copy of emmett’s Folding Cube model from Thingiverse. That model works wonderfully but assembly was a little difficult both because it was physically hard to…
The semester has begun and we are back to teaching calculus. Later this semester we will cover Volumes of Solids of Revolution with the “disc method” and the “shell method”,…
Does it count as a print-a-day print if something I designed and sent to Shapeways was delivered today? I think it does, at least the first time it happens! Our…
Still underwater with the first week of school, so today we’re printing emmett’s great Folding Cube model from Thingiverse. The eight pieces print separately and then snap together with conical hinges to…
So the spring semester started yesterday, and I’m already fully underwater with one calculus classes, three 3D-printing classes, and a lot of trips to plan. So today we print something…
My son loves pi. The number. He and a friend at school have actual arguments about who has memorized and/or written down the most digits of pi. The other day…
Henry Segerman is well-known for the intricate mathematical modeling that he designs and prints at his Shapeways shop. So to put our Replicator 2 to the test, today we printed…
