A set of knives inspired by Metro 2033 series suitable for LARP games.
Print all knives with black flexible filament, Flexfill 98a is a good choice. However, if you have softer filament, try to use it instead.
You need to generate support material for V1. Increase the space between the supports and the model in Z axis (0.2mm should work fine for 0.15mm layer).
Use preset for semiflex or flexfill 98a or print deadly slow.
Don't forget to loosen the idler on your printer.
The holder for V1 looks fine when printed with Prusament PLA Mystic Brown.
Glue all the flexible parts together with superglue, use M3 screws for the holder.
Paint the models with silver colour and rust. Do not use acrylic paint (it will peel off), instead use model paint (I used ModelMaster and it worked really well).
