Back story reasoning:
I like clustering the 29 mm 40-120 G 138 loads.
Problem is that the delay end of the casing heats up quite a bit.
Due to the lack of insulation.... The casting tube is also the liner.
I've flown about 6 of them. No blister so far ( knock on Wood).
The cases are being discolored by higher temps.
I recently purchased a 3D printer and want to make use of it in rocketry.
I designed a simple plug in Tinker CAD and It fits nicely. Will it hold up to internal temps using PETG?
The motor only burn for 1 sec or less.
