As I'm experimenting with the best material for a specific mechanical application (3D printed wheels on bearings in a suspension slider), this is super useful: I ordered both Shore A and Shore D durometers. I would be very grateful if you can include a Shore A and Shore D readings in all your incoming filament reviews. Although it doesn't tell the whole story, a reading still tells so much about a material's properties.
I bought a set of spherical dice at least 15 years ago, I wouldn't be surprised if someone took your idea and is selling it, but they are a bit late to the party.
Can you open it (without breaking)? Just curious, probably the hole is like a dual polyhedron, that's the original design. I never found that rounded design for hole before. But as I mentioned, it's not that important from my side, since I am not sure if there is a design copy..
@@MyTechFun I'll see if I can find them, it's been quite a while since I thought about them. From what I can remember rolling them in your hand felt like the ball was going over something then dropping, but that may been been my imagination as I didn't have anything to compare them to.
@@MyTechFun I just happened across them today, and somehow remembered this comment. I'm afraid I can't open them non destructivley, but I have been rolling them around carefully and listening/feeling for the balls movement. I would expect that if it was a simple octahedron the ball would shift to the next corner sooner than it does. Slowly turning it from the 1 to the 3 or 5 (on the bottom) the ball doesn't shift until the 5 is almost straight down. Other positions seem the same but 1, 5 and 3 have clearly marked face centers. It also rattles more easily than I would expect from the octahedron when held in one of its natural orientations. I know that's not very definitive, but I'm not feeling prepared to break one open just yet😉. It makes me wish I had access to that object cat scan set up various youtubers have been showing off lately though.
Good job sir, thats something new to the 3D community which really add value
I always wondered if the cold effected the "hardness" of 3d printed plastics. i.e. frozen plastic=brittle.
Great video. Keep it lit.
Hardness is a different property from brittleness. It's all a little irrelevant as all plastics are soft compared to just about any other material.

very informative! thank you for sharing your expertise!
congratulations from Brazil!
Knowledge ... thanks :)
Super helpful content, as always! Which lathe is on your metalworking desk?
Thanks. Both SIEG (Milling SX2 and Lathe SC2)
thanks! :-) really informative.
maybe the resin cured more with heat?
Yes, probably
Yup, post-curing with heat enhanced the cross-linking.

They have stolen your design, disgusting
It is very similar, however I am not 100% sure that it is my design. But if it is, all they have to do to use it legally, is to give the attribution.
