This is a holster for the famed Liberator Pistol.
Editing is acceptable and I highly encourage you to reshare your iteration.
There are TWO versions here:
One with a bolt on style clip - holsterbolt, holsterclip
One with the attached clip - Liberatorholster
fit a 30mm x 10mm x 4mm Neodymium Magnet in rectangle hole with your glue of choice (ABS glue).
Glue the Magnet Door over the top of the magnet to hold it in place.
(Optional) for the bolt version, use 10mm M3 Bolts and nuts to fasten clip to holster.
By law, the pistol requires a steel block. The magnet will secure the gun to the bottom of the holster.
