My patent attorney tells me that I can share inventions that are in patent-pending status. And I have some that will never be patented.
None of these are actually for sale now (well, I would sell you a Switch Minder made on my printer - but if you are reading this forum can make your own) - so I'm posting the link here in "Showcase".
The white plunger seen in the video was printed on my Plus. It was VERY difficult working with the SemiFlex filament to get that thing to print at all. The black version in some still photos was produced by a commercial 3D printer using a different process; it looks great but cost an arm and a leg.
