FYI 3D Printed Cap Wrench for On The Go Portable Water Softeners

[Neal]

I was at a CG recently and @ARD couldn't get her water softener cap off. I have large channel locks (pliers) that we used but I was in fear of damaging the plastic cap. A neighbor happened to be aware of various accessories by On The Go Portable Water Softeners and one of which is a cap wrench. Works like a charm. It's cheap on their web site, add shipping and it can get a little more pricey but I figured I haven't done my 3D printing hobby in a while so why don't I whip up a design and print my own. Voila:

On The Go Portable Water Softener Cap Wrench by NealC

I have a water softener for my RV/motorhome by On The Go Portable Water Softeners. The cap can get stuck from salt. They sell a cap wrench which you can buy from https://www.portablewatersoftener.com/shop/water-softener-accessories but I decided to design my own. I decided on handles on opposing...

I highly recommend their large water softener, it's been a life saver out west and other locations. I now use the test strips to test the water at the city water spigot prior to connecting to determine if the water is hard or not.

EDIT: I forgot, we put food grade o-ring lubricant I had on the o-ring under the cap and that solves the problem of the cap sticking. This is also good for your dump/gate valves when the time comes they need to be lubricated.

Thanks @Neal - The cap wrench is printing as I write this. Also, thanks to you and @redbaron for getting me into 3D printing. Since January I've printed many different and useful items while learning Fusion 360 and having lots of fun!
