Heyo Istvan !
(Totally don't mean to derail from bugsplatting, it seems like everyone here is doing a rad job and loads of good stuff being made!!)
I sent a message to Shapr3D's Facebook page! Addressed from a junior-year Mechanical Engineering college student seeking Industrial Design for grad school, who is amazed by this app (and whose nickname is Shaggy). I was wondering if by any chance you may have seen this message, and if we could talk?
No worries either way, I totally understand you guys must be wicked busy-- and by the sounds of these posts, it definitely seems like bugs are doing what they do best and causing some trouble here and there haha. But you guys are doing great, and I'd love to speak further if at all possible !
