Thread: Plexiglass razor rack and microscope stand

Usually one off stuff or short runs for biomedical research at universities. Lots of medical grade titanium 64 and CP, cobalt chrome , and 316L stainless steel; occasionally copper, platinum, and aluminum. Since they have to milled under medical device guidelines, a tiny mistake on my part gets expensive very quickly. So I always test with something cheap before sending the design off to be milled professionally.
The easiest thing I've built was a set of tools to be used under a microscope for a guy who had lost his index finger.
The hardest thing I've built was picoliter pump that could sit on the tip of your pinky finger.
And there have been a lot of fixture devices, specialty fasteners, and just oddball stuff that they need for just a one time test.

Edit: I should probably say that this stuff is for cell and tissue research. Nothing that actually goes into a living human or animal.
