Howdy again y'all!

So here is another thing I've made with double piston extenders.In this build I've used 3 different types. vertical. horizontal, and pushing up. only single pistons were in the t-flip flop toggle switch. I also used an arrow detector as the activator for the opening of the mechanism. there new to me, so if anyone has a better idea, please let me know. it would be greatly appreciated.

Enjoy Y'all!!!
