D12 V-Weight Hole Protector

I have had some warping of a V-Weight on my double 12-liter SCUBA set, this is made in pure lead. The warping happens partially due to a very loose fit of the lead onto an M8 bolt. This part aims to protect the V-Weight hole from rubbing along the M8 bolt.

Helps protect V-Weight lead hole somewhat, but V-Weight will still bend and warp as it has no support on the tanks, that may be a future project. A tight fit on M8 bolt, must be pressed down.

Can probably be used on other sized tanks, as long as the V-Weight hole is 16mm diameter.

Since it is printed in PLA, I expect it to deform/slowly decompose over time.
