D12 V-Weight Hole Protector
thingiverse
I've been experiencing some warping issues with a V-Weight on my double 12-liter SCUBA set made from pure lead. The distortion occurs primarily due to a very loose fit of the lead onto an M8 bolt, which is intended to safeguard the V-Weight hole from abrasion against the M8 bolt. It helps protect the V-Weight lead hole somewhat, but the V-Weight will still bend and warp since it lacks support on the tanks - this might be a future project. A tight fit on the M8 bolt requires pressing it down firmly. This part can likely be used on other tank sizes as long as the V-Weight hole is 16mm in diameter. Since it's printed from PLA, I anticipate it to deform or slowly decompose over time.
