These files are to make a bath bomb mold to make donut shaped bath bombs. The mold is for people who make their own bath bombs and is designed to be used by hand.

You will need to print 3 pieces to make a complete mold: 1 sleeve, and 2 inserts. You can either print the insert with hold twice, or you can print one of each of the inserts. The auto-hole insert will enable you to make bath bombs that have a hole in the center without you having to push bath bomb mix through the hole to create the hole in your donut.

Finished bath bomb diameter is approximately 3". Finished weight and depth of bath bomb is dependent on how much mix you put into the mold. When I make my donut bath bombs, they are approximately 125 grams / 4.4 oz.
