You could resin print it, mold it, do a cut mold, and pour some resin. Email Smooth-On if you have any questions about this, especially if you have a Smooth-On or Reynolds Advanced Materials close by, or even if you don't. I think $100 gets you free shipping, and $40-50 trial size silicone, ditto $ in trial resin, maybe $13 inhibit-x, and some mixing cups and sticks (deli 32oz @ $0.19/ea, sticks slightly more) would get you close. You'd need to post print cure the fuck out of that print (uv and isopropyl alcohol bath) and test to make sure there's no cure inhibition though. Tin cure silicone is apparently less sensitive to that, though, but doesn't last as long and isn't skin or food safe but is much cheaper. For food and skin safe and cheap and easy platinum cure, I recommend Sorta-Clear 37. You can see how you have to cut the mold if you end up having to for removal and you can clearly see how the resin is pouring in. They can help you with resin choice; I'm just getting into that. Be sure to get something heat resistant/heat tolerant. IIRC there's something-ONYX that deals with heat well but the cure is long and requires post processing (bake in cheap secondhand toaster oven outside).

Alternatively, FDM it in a slippery material for retardedly cheap @ $15-20 a spool and just replace it when you feel like it.
