A low profile version of my previous design.

I like to store my rocket fuel and black powder in these 1000ml jars. They have a convenient double lid and seal pretty well, so I designed this container to keep my chemicals dry. It mounts to the jar lid from the inside and is designed to be low-profile and universal. The dimensions of an assembled container are 80mm x 12mm.

Hardware

• 3x M3 bolt (≥ 5mm)
• 3x M3 nut

Printing Instructions

The printer profile already has all the right settings. Generally, I'd recommend using a default preset for a 0.2mm layer height, with 3 perimeters. I like to print stuff like this from PETG, but PLA will probably do just fine, too.
