Spanner for seawater filter (Vetus, Allpa...)

Please post your print 💖.

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
