Canning Jar Lid, 3D Printed by DrewTM Jul 25, 2012

Description

This is a one-piece, wide-mouth canning jar lid that can be printed on a Rep-Rap, Makerbot, or similar 3D printer. I made it to close a jar of hydrochloric acid, which will attack metal but not ABS plastic. The threads work very well.

This lid has the best feeling threads of all of the ones I've printed thusfar, great job!

DIY 3d printed lid for a jar of hydrochloric acid...seems legit. :)

Instructions

Print upside-down, with the flat top stuck to your build platform and the threads facing up.

If it doesn't fully seal the jar, you can try smearing or drizzling a little paraffin wax around the inside edge of the lid, where the jar lip touches.

Both ABS and paraffin wax have good resistance to hydrochloric acid, which is what I made this lid to contain.
