The Crown itself is one singular piece with round edges at the bottom as to not agitate your forehead as well aesthetic purposes. No Supports needed and the large base should lend itself to good bed adhesion.
Jewel with Resin Mold
The Jewel comes with a compatible mold shell to allow for easy mold creation and resin casting. As always, remember the below values represent the exact values of the mold/casting but you'll need to mix slightly more to account for resin and rubber left behind on the cup, mixing stick, etc.
Combined Gem Volume: 3.6 mL
Combined Gem Rubber Mold Volume: 10 mL
The sizing ring is essentially the bottom of the crown sliced off, it allows you to print a quick base that you can try on to ensure the crown fits, you can scale it as you wish. Note that while you shouldn't encounter any problems with scaling uniformly or non-uniformly, just remember to scale the jewel (and their mold shell if you are resin casting) to the same dimensions.
This means when you load the jewel into your slicer
scale them first
then you can reorient them for printing
If you would like to download demo versions of any of my models, you can find them here
You can read more about this model and my experience building it here.
All my models are designed with a focus on hidden seams, ease of assembly, little to no support printing, and accuracy in mind.
If you need any help with the printing or building process, or you just have a prop you would like to see me do, feel free to email me.
