Pool Filter Lock
by drmatrix, published
Seems they no long make a filter tightener for the type of pool filter canister I have - so here is one. Time will tell if it withstands the Sun, chemicals and time.
Seems was not as robust as planned - so - here is version 2, It is slightly thicker at the nut-capture, as that area was cracking - also made the hole for the nut slightly smaller and then used the technique of a hot soldering iron to melt the nut into the tighter hole.
And changed from 4 finger grips to 3 finger grips (4 was too many got in the way), are a little longer as well.
Sliced @ 0.2mm with 3 perimeters, and 25% infill. Then I fused the outside with Acetone until was smooth - hopefully to prevent intrusion of "stuff"
