About this 3D model

This is one of my most stupid ideas ever! A compact gadget which can be used to play mini golf if attached to a bic pen. It can be a useful mini golf balls transporter. Now, imagine this at school: you're at school during that boring hour, you take your pen with this assebled, you take out the balls from the big part, you draw a game on a sheet of paper and you start playing. P.S. attention to the material supports, i personally printed the big blue part in ABS.
