My account and posts from my previous tomato cube mold designs from Printables got taken down (probably VPN and/or Linux usage). Nevertheless, I found a better platform on Thangs.com. The search is much better and it searches other platforms as well as its own website.
I have linked my new and improved uploads with even tighter tolerances below for you guys to download. V.3 introduces a completely cube interior with none of that angled walls v.2 had.

As another option, Yeggi also is a meta search.
Yeggi’s UI is even worse imo but I’ll keep that in mind.
