Thanks... Round 2 is in the works now that the concept is proven. I might do a build thread, or at least document cost comparisons if there is an interest.

You’re looking to do cost comparisons it to get it below $25?

This is pretty awesome, even at the outrageous price of $28.

Nice... Never thought of reading it like that! Version 2 is done (for Lampshade Junior), I just need time to put together the documentation comparing costs to a "professional" product, and costs without 3d printer access... It does use an excessive and arbitrary amount of 3d printed pieces right now!

Version 2 post is up in it's own thread.

Respectfully,

Right side kidney dump... Same on my second version.

I used to skydive, where the pilot chute was on the right, so that's just the natural position for me to put it. No reason I couldn't do left side, or both.

So how did you attach the parts to that tube? Do just cut and pinch it? Or did you use some kind of sealing process heat or adhesive?

Carefully cut the 1 inch hole for the flange, then the flanges from DGX us a 2 layer gasket... I only used a one layer gasket cut from rubber sheet. My gasket is not perfect, but only seeps under a significant pressure differential. Just did a 50 minute shallow dive last weekend with no visible leakage.
