I've been loving the new fermzilla tri-conical fermentor, but once the lid is on the collection chamber, it can become nearly impossible to remove by hand. I created this slip-on collar with flat sides that can be used by hand to get a better grip to loosen the lid, or be used in combination with other tools to loosen a stuck lid.
The gcode file is for the mini/mini+ and has two color changes on it. I set 4 perimeters and and a 40% infill w/ a grid pattern for added strength.
||Update 2/13/23: added a version w/ 2 handles for ease of use||
