Were those TPU flap valves printed in place? Almost looks like they were.

  Are you sure? yes | no

Hi Dan!

The intake / exhaust valves were glued to their respective gaskets using a very small dot of thick cyanoacrylate glue.

Wow, that works great. Now you can have an automatic "charging" station for that balloon powered car you designed: https://www.youtube.com/watch?v=wkyOi47r9Io

Use of the silicone baking mold is brilliant. At first I thought that was a 3D-printed part (made me wonder about durability) but this a great source for it and smart to start with and design the structure around.

Hi Mike!

Thank you so very much, I'm glad you enjoyed it!

It is a true story regarding the baking mold, and I truly had to replace it!


Thanks again,

Greg

The inspiration to design, 3D printed and assemble "Marblevator, Paddle Lift" came from the Laurent Chate' Meccano ping pong ball lift 4.
