  1. FOR PURPOSES OF THIS SECTION, "THREE-DIMENSIONAL PRINTER" MEANS A COMPUTER OR COMPUTER-DRIVEN MACHINE OR DEVICE CAPABLE OF PRODUCING A THREE-DIMENSIONAL OBJECT FROM A DIGITAL MODEL.

Not an American, but it really reads like they redefined 3D printer as meaning "literally any kind of cnc machine".

Thanks. Hard to say how long it took, I started exactly one year ago. I first started with a wooden box, but binned it as soon as I got a 3d printer. Then there were alternating periods of CAD, printing and tinkering with the electronics; and this project sitting in a box because I did other things in life. ๐Ÿ˜…

It's basically a 10 inch screen matrix for SLA printers, a 130W blacklight lamp from Amazon and a ground glass for even lighting. The lamp gets very hot, so the two fans blow air over and under it (split cooling channel). The parts touching the lamp are printed in Greentec Pro Carbon, electronics box and cooling channel are printed in Geeetech matte PLA.

Attempt at thickness caliper for instrument making. (feddit.de)
 

Printed with greentec pro carbon (stiffest filament I've found so far). 8 perimeters, 45% infill, top/bottom 2mm. The arms are 230mm long. The design and material of the C frame are still not stiff enough to be usable, but I'm pretty proud of the lever design. Easy to put together, durable and doesn't wiggle to much.
