Well Michael, sometimes sharing something for free will bring you something in the end? That said, I would like to share something of my own.
I tried to print your resin tank comb, but since I am a newbie in printing on the Form 1+, the print failed. Some of the teeth cracked, because they are relatively thin, with little support. So I decided to draw my own version of the resin tank comb. It’s based on your idea, so all the kudo’s go to you! 
Here is my design (in Rhino):
I decided to make a filter like surface in the upper part of the resin tank comb. Since I’m a big fan of hexagonal shapes, I couldn’t resist to make the holes like so ;).
The advantage of this change, is that the upper part is much stronger than the original idea. The holes are big enough to pour the resin trough, but I think you need to move the resin tank comb slower than with the original comb.
Another small think I decided to do differently, is the size of the upper handle. I made it a bit taller, so one can grab it a bit more conveniently.
So here’s an overview of the orientation in PreForm:
The first attempt to print the resin tank comb was a succes, as these pictures can tell:
Back to the subject of sharing; I decided to share the files of my resin tank comb as well. To start, here’s the STL file:
And here is the form file, if someone would like to use my orientation:
I printed the resin tank comb in 0.1 mm layer height and in white resin.
I hope this is a nice contribution to your excellent idea, Michael? Thanks again for your initial ingenuity! And I hope this is helpful to some of my Form 1 colleagues?
