alt Hacker NewsOh absolutely!
I would not actually use this for uhhh, repeatable measurements over any extended period of time!
(If that were the case, I'd recommend re-printing it in a slightly more stable material, or just CNC milling the mounts out of aluminum using some of the ~$1-2K aluminum desktop mills and using some aluminum extrusions as the base.)
I suspect they'd be fairly cheap to get made at somewhere like JLCCNC. Or maybe get them to 3D print them in metal for you?
I wonder if they have enough different metal choices that you could build a thermal expansion compensated version? https://patents.google.com/patent/US8292537B2/en
