The Digger was one of the first designs I actually made to sell over social media back in 2020, This was the little write up we had for the design, Digger. it was not a success and I think you could count the number I sold on one hand. I did make a simpler 4 balloon version over on model of the month over on Balloon Chat, Model of the Month Digger.
This link has both Digger designs to view, Both Diggers.
And there was a pretty elaborate one I made as well that can be seen here, Elaborate Digger…. he he.
