Stomp Rocket w/ Spring inserts

I saw a comment that wanted a spring for the plunger to come back up. I decided to try my very first remix and I attempted to insert a space at the bottom of the launcher to accommodate a spring. I also inserted a rod like spacing for the spring. (I can probably make that shorter). I have not tested this myself yet with a spring but do let me know in the comments how it works out for you, or more edits I can make.
