This is a remix reworked from memory. I saw the original a long time ago and couldn't find it by searching. I apologize in advance to the author of the original - write me a personal message - I'll add a link with pleasure. The remix is that in the original the crossbars were pentagonal - which is inconvenient - here they are hexagonal. And in the middle there are additional holes to save a little plastic.

P.S. By the way, the general photo shows the original, my version is a close-up photo with blue details and a render.

PPS - the author of the original model has been found - hurray
