This is am Airsoft Gun stand for the KWA MP9 and other versions of the MP9.

NOTE: Horizontal Expansion should compensate the Expansion of the filament, please adjust accordingly. If you haven't set it, and you print with the print settings given, try setting it to -0.2mm this worked perfectly for me. Should this setting not be present, print this model at 99.5% scale.

This model got created in Plasticity, the files for it are inside the rar file in the attachments.
