Marine Deck Filler Key - Magnet mount

Bi-square deck filler key with embedded magnets for mounting.  If you don't require the magnetic version I have also uploaded a non-magnet version.

These deck fillers are typically used in marine applications for both diesel and water tanks.  This type of key is much easier and less cumbersome than using a winch handle.

Suits normal 18mm bi-square filler sockets.

I printed this design in both basic PETG and in Prusament PETG C-F (carbon filled).

Even the prototype in basic PETG with 2-perimeters and 15% infill seemed strong enough when tested on the diesel cap but my final print was with 5-perimeters, 20% infill and PETG-CF.

I fitted embedded magnets in this design to enable mounting on my mild steel diesel tank (yes, old boat with mild steel tank but still in good condition so retained).  The print should be paused (photo) at 4.20mm to enable two 10.00 x 3mm magnets to be installed.
