Description
A simple tool to loosen the lid of your seawater filter, which is usually insanely tight due to negative pressure.
I've created both versions:
Spanner for seawater (single) - for the lid with one tab
Spanner for seawater (cross) - for the lid with the two crosswise tabs
If you like this design, please post your print with a picture.
Anybody willing to support with a small donation is more than welcome ;-)
