Fusion 360 vs Solid Works – Does Fusion 360 work?

by NKCubed

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?

Custom puzzle design <=> Patent?

by Mixomycetes

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?

Kind regards,
A confused soul
