alt Hacker NewsHave you tried SolveSpace? It's easily my favorite open source CAD program. The main things it's missing are shells, fillets, and chamfers. But I've been able to 3D print quite a few parts using it!

Yeah I actually have. I really liked the concept, but I designed a cylinder with many holes (think a robust sieve) and it just crashed when the number of holes grew too great. Even the OpenCL/MP version. I felt it being unstable in other ways too so I did not make it my go to tool. Sadly it also seems it's not being developed much.
EDIT: Missing fillets and chamfers we're also a big problem for me - probably I'm just a newbie maker and want unreasonable things, but still.
Just checked it out [1] but it appears the last version released was in 2022? Makes me wonder if it is still active.
Solvespace is nice, but missing fillets and chamfers is kind of a deal-breaker. Last time I tried it it also had issues with small holes turning into diamonds.
That said, pre-1.0 FreeCAD had a terrible UX so it was the best FOSS CAD option.
With the 1.0 release of FreeCAD the UX is much better though. There are still a few WTFs (e.g. it took me quite a while to figure out rollback is done via right-click->set tip, or something like that)... But overall it's better than Solvespace now.
You might want to check out Dune3D. It advertises itself as combining the constraint solver from SolveSpace with a OpenCASCADE geometry kernel supporting fillets and chamfers. :)
Haven't used it much apart from some minor tests (I tend to prefer MoI3D, but that's in a different category in several ways...), but as far as FOSS solid modelers it seems like the most promising to me. I do remember some small UI quirks, but overall it felt very approachable and streamlined, and looking at the GitHub repo, development is active. FreeCAD IMHO is just too sprawling and complex, with seemingly little tought paid to UI/UX.
