Hellboy Bullet

I've wanted to make some cool Hellboy bullets for my prop gun for a while now. I've finally figured out how, using an arduino and a resin printer. I printed these on the elegoo mars. You can print them on fdm but the quality will suffer and the cone won't be transparent. If you resin print them you will need a drain hole in both the casing and the cone. Because they are a "cup" shape they have problems with suction forces in the vat, which will lead to distorted prints. Check out the video here: https://youtu.be/a0c7XtRE4GE
