I purchased a KBS 17-in-1 Bread Maker. If you add the ingredients to the pan when it is out of the bread maker, there is a possibility it could tip over.

I designed a base:

• A flat base to stabilize it.
• A hole for hanging
• A cylinder to fit the base of the pan.
• I added four pegs for additional support but they were too short and you probably don't need them
• Added text of "Breadmaker holder" in case someone is dying of curiosity as to it's use.

It was about a 5 1/2 hour print on and ender V3 Neo

I measured the base of the pan with a cheap digital caliper and enlarged it slightly to be safe (Maybe 1/8 inch or so). It turned out to be a perfect fit and adds a lot of stability to the pan.

I designed it in Tinkercad.
