SummaryModified silencer for 4,5mm bullets with M10x1 thread, perfectly fits on Baikal MP-61 etc. Length can be adjusted by the number of segments you're printing. Use max 0,4mm Nozzle with 0,1mm layer height, otherwise thread is not high resolving enough. If possible check the avoid crossing holes function in your slicer. I recommend ABS, Nylon or PETG for printing. With a slightly flexible filament (not PLA) it could be also screwed on other M10 threads. The more segments you print, the more effective it gets. You might need glue for assembling!
