Based on commercial tennis ball savers. Put up to 3 tennis balls in, screw down. You will need a 3.5mm thick o-ring in the groove. 65-70 mm internal diameter. lube it with a little vaseline. This creates an air tight seal so that when you screw down, the volume decreases and the pressure goes up. I used these o-rings.. https://www.amazon.com/dp/B0C81718Z4?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 I experimented with printing my own TPU o-rings, but didn't have much success. I printed with PETG. the gold accents you see in the picture were just a little extra modification done in my slicer.
