I wanted to turn a kayak air bladder into a camping shower that would hold a few gallons instead of a few liters. Rather than acquire a sink sprayer I thought why not learn a new skill so...

I remixed thing:5199539 and decided to finally learn to use openSCAD since customizer wasn't working.

Jumped in and added some new features to the box with fun customizations. You can control the dimensions to fit your O rings, it takes one on the plunger to seal it off and another after you put in the hose nipple to seal the threads. The spring dia is also user set.

I was pretty thrilled to do the double if loops for the spray hole array, it's got a lot of parameters to mess with because... why not.

Initial design used a super ball as a valve but the large surface area made it hard to get a good seal and even harder to push it out of the way.

I may work on the code a bit and get the origin for the holes to start at a more predictable spot and I haven't reworked the part selection, my version only generates all parts in the printer ready parameter.

V4.5.4 added O ring channel on hose mount, it's water tight now! Lots of new parameters to set. Hard to determine exact compression of o ring to seal, need to do a bit of engineering on that.
