The Kriss Vector Gun model is 3D printed using a 0.2mm nozzle, because when scaled down to make a keychain, the details are extremely small and a 0.4mm nozzle cannot capture them
I have created an additional version for a 0.4mm nozzle, but if the print quality is still not good, you will need to scale the model up
The printed parts require gluing to make them sturdy and to eliminate any gaps during assembly
