The file 'LCT Airsoft PBS-4 24×1.5mm RH To 14x1mm LH Thread Adapter 3D Printer Model' is (STL) file type, size is 4.2MB.
Friend lost the thread adapter for their LCT PBS-4 suppressor/tracer body.
The original one has lock pin holes, not detailed here as the adapter was lost and I didn't have access to the gun while measuring this.
This adapter screws on just like the SOCOM Gear models. You must use something long enough to engage both driving slots at the same time, like a 1.5mm hex key sideways, otherwise you'll break it. However, it's quite strong once installed.
This also means you'll have to index it manually, with shims or the like.
Pictures include a cursed image of the PBS-4 installed on a SCAR-H.
Print orientation should have the dead side (side with an unthreaded 2mm stickout) on the bed, driving slots in the air. I recommend printing this solid (100% Perimeters) in something tough, like CF-PETG.
