So I know EVERYONE uses solid works to design puzzles, and I don't mind the price, but I'm a Mac person so I would love to use Fusion 360 instead if the programs are comparable. Are they? Can you do puzzle design in Fusion 360 the same you would in solid works?
A while ago, I designed a 3D-model of a (very rudimentairy) skewb -with a ball core and 4 rotating fixed corners-, for training my 3D-design skills. After printing it (for non-commercial, own use) I'm quite happy with the result and I would not mind sharing the design files, so others may play, remix or learn from them. I'd love to give something back to this community
However, i noticed that there is a USA-patent from 1994, on a puzzle ball, but covering any shape mod, thus covering this type of puzzles (i think). Would publishing my stl-files be allowed by the patent *(Link to relevant patent: http://www.jaapsch.net/puzzles/patents/us5358247.pdf ) and/or by Thingiverse 's code of good conduct? I'm not so good with understanding legal texts...
How long are patents typically valid? 20 years? 25? Indefinitely?
Here some claim it's expired:
Was it renewed?
If it is ok/allowed:
- Should i (in theory) ask permission to someone?
- What licence should it minimally be given then? Is there a restriction?
