Can you use a silk rose? Some of the fabric flowers at the craft shop are quite convincing - your product looks great but the flower is a bit clunky.
I'm all about 3D printing stuff but I've got sugar skulls that are really tiny and would fit perfect in a ball top, ditto a ton of other ready made products I'm sure.
Also any reason for the collar on the bottom of the balltop instead of just casting it round then drilling the threaded insert into the ball itself?
Typed a message and it got erased, apologies in advance if I'm short:
Yes, anything it technically feasible, I'm a little worried sugar would break down but I'm sure there's a coating or something that can be applied.
The main reason I use 3D printing is I can a) make practically anything and more importantly b) can scale, orient, and position the item precisely. This is doubly important because of the inherent distortion of transparent spheres.
The collar is intentional, because of technical details it was designed this way. When creating the process, I didn't see a reason why I should have a secondary operation for the insert. Why not only have one step and cast it directly along side, you know? It's not easy to make a smooth sphere, then make it perfectly clear, then remove seam lines, suspend arbitrary things that float, place a metal insert that sinks at the surface, and remove bubbles. These aren't your basic ball tops. I think the collar is both distinctive and honest to the process of making of these.
