Hey, Lex. Awesome design (as usual). It is finding use here at UCDenver! I see two files. Is the slightly updated one just with some material removed for ease of printing? Thanks!

Can you confirm that the slice spacing is 1 mm increments?

Hi Phil - they are spaced at 1.2mm increments.  Each "fin" is 0.6mm thick and each space between is 0.6mm.  I forget why I did this instead of 1.0mm, it might have just been easier to print with the spacing a little thicker.  The editable design file is here:, would be trivial to edit to 1.0mm spacing.  If you aren't familiar with TinkerCAD I can do it for you too let me know.

I'll also throw out that the specific dimensions of the physical part will depend on the printer you use and its tolerance

Hi!  Yup I printed these at - the white one is Somos GP resin, and the clear one is Somos clear resin.

Hi There, 

Would you be okay sharing what commercial supplier you used to get these printed?
