Airsoft BB gun trap.
Model has two tabs on either side to allow a paper target to be clipped on.
I am using a tube connected to the rear to cycle the BB's back into a bottle. I may make some separate tube attachments or adapters.
Use lightweight BB, maybe .12 or .20 I found that .30 caused some damage to the coneif fired too close.
My printer volume is 240x270
Model could be printed in two parts if required.
