About this model

This is an adapter for the ka-56 grenade so it can be loaded to a m203 launcher. The model needs to be CUT VERTICALLY AND ADD CONNECTORS you want. Apply glue on both sides and then put both halves on the airsoft grenade. Use some kind of press tool for maybe an hour ,like in the foto ,to keep both parts close ,so they can stick to each other. Depending on the brand of the grenade you might need to change a little bit the dimensions of the adapter ,so make some measurements before printing. DO NOT FORGET TO CUT THE MODEL AND ADD CONNECTORS!!! I used PLA BambuLab basic and it works. Edit: 2nd design is already cut and ready to print it.
