I’ve Recently uploaded some 3D kit-bashing sets for my $10 Patreons. Technically 2 sets broken up into 3; Some hard surface city designs made in Fusion 360 and some organic flower / plant shapes made in Zbrush. The .OBJ packs are royalty free.
You can come download all my 3D puzzle pieces by joining my patreon at the $10 tier level. I’m planning some more sets in the future, both Organic and Hard Surface designs.
Super fun and useful !
