Summary

A friend of mine wanted to spice up her soap making and have a more precise soap molding solution. She wanted to have a long 5x7cm ellipse tube as long as 30 to 60 cm...

I suggested to have a modular 3d printed mold what you can use to build as long as you need. I used PETG so it is strong and water proof...

I printed 2 pieces what fit together and can be screwed using M3 bolts and nuts.
These pipe segments can also connected together using M3 bolts and nuts.

You can unscrew the mold after the soap has set and just pull it apart and slice up the soap I guess :) ...

added an end cap/cup what can be screwed at the bottom of the mold,,,

Enjoy...
