If you’ve seen my yellow ball launcher tank already, then there’s nothing really new to see, I’ve just tweaked it a bit to get it ready for LEGO Ideas. When I had the tanks on display at Brick Universe, I kept getting asked where they can be bought, how to build them, etc. If you fall into that category, then now is your chance to lend me the support necessary to make that happen . Thank you for your consideration and support! .
