Cast Iron Dutch Oven / Frying Pan Lid Spacer

I made the mistake of putting a lid on my Lodge cast iron dutch oven before putting it away and the oil inside the oven went bad. After scrubbing it out and re-seasoning it, I designed and printed these spacers to keep the lid from sealing on the dutch oven and crating the same problem again. It also works for the Lodge cast iron frying pans as well. It seems the angle of the sides is the same for the three Lodge items I have (10" pan, 12" pan, 7qt dutch oven).
