Introducing what I believe to be the first open-source Mega XL BCAR. How I made it is hardware-less, but I'm sure you can find metal parts for the bearings and rods. It has 9.5 degrees of rotation (I think). I have no clue what anyone can put this on as of yet, but I'm cooking up something that will hopefully be done in the near future. This can probably be stacked on top of itself to make a 10x3 BCAR, which would probably be appropriate for how big the Mega XL dart is. Go wild with it, just credit me if you end up putting this on something :)
As for printing these, I printed the main body with slim tree supports, it takes me around 5 minutes with pliers to get everything off. The bearings and rods obviously don't need supports.
