.357 revolver chamber safety marker
thingiverse
Designed for Smith & Wesson Model 686, chambered for .357 Magnum\.38 Special. Blocks all chambers and gives an indicator on each side of the cylinder that the revolver is empty and safe. If printed laying down the indicators might be prone to breaking off due to thin size, it might therefore be advisable to print it standing up. Small flange on each side to make extraction of the marker easy. The model should also engage with the extractor. There might be some stringing if printer settings aren't completely dialed in. Have printed and test fitted with both PLA and PETG.
