We poked around about doing this a year ago but where to start got us hung up! Due to the DRD Strange shape and size larger that the makerbot , 3d printing the whole shell as one piece was not possible. However drawing details and then applying them to a hand made oval body is totally doable! This is the start of the project , I wanted to get something together that could be shared with the rest of the community. Once details are glued on then you can use a DREMEL to dig out the cavities between details. This is what makes them POP!

It’s looking good! Thanks for the update Josh!
Ok update for today, the last of the latex has dried and I lost count of coats, maybe 13 or 14ish. I taped off the body and separated it with a tape divider. Next is fiberglassing the mother mold into two halves:)
I will give this guy a hour to harden and then switch to fiberglassing the other side. I will let that harden an hour then use a deemed to shape the flanges and finally pull the mold apart for its first casting!
Side B was just fiberglassed with 2 layers of resin and Matt. The seam has a distinct lean so there is no possibility of assembly backwards.
So Side A hardened fine but side B has not yet likely because the temperature dropped into the 50s shortly after I laid the fiberglass. If it is not hard by morning I will need to lay a HOT coat on top of this. That’s where you double up the hardening catylist and paint it on top of the partially cured resin to harden it up. I moved the piece inside where the temp is 67 which may help as well, we will see
Checked this morning, it is 90 percent hardened so I think a once over with a hot coat is a good idea and that will finish it up. Then I can pull everything apart and start the first casting ! Excited.
All molds are finished, now before any casting they need to be coated with a release agent to prevent sticking and then I can start. I really dislike this setup, I prefer urethane or high strength silicone and it takes the pain in the axx out of this process.
