I recreated GregNetDesign's beautiful Wingspan resources in Fusion 360, with a couple changes:
The pieces are thinner, about 1/2 the thickness of the originals (faster printing, less filament)
The grooves are deeper, making them more pronounced.
The pieces are two-sided, which most printers should handle just fine with bridging.
I designed a different "Berry" resource from scratch.
Note: because there are now grooves on the bottom as well as the top, it's extra important to have good printer settings for first layer adhesion and for bridging. A level bed, a slow first layer, and no elephant foot compensation are suggested, especially for the worm where the first layer is multiple separate pieces.
