Design a mechanism for a push-out and retract mechanism for a ballpoint pen
Budget: €250 – €750 EUR
Dear
I'm looking for someone that can design a smooth mechanism that allows to push-out the ballpoint from a pen by pushing a button on the side of the pen, and retract by pushing the top of the pen.
You should also be able to make me a working prototype
