2 Levers and a button for your what ever that it is you're working on.
Subsurf mod. has not been aplied so feel free to modify and what not.
Would be better if there was some simple parenting, rigging and constraints added.
I've tried to figure out the rigging a lot by watching several tutorials and testing it my own but I have never managed to do anything with it, Not even anything simple as these. Feel free to guide me to some very VERY basic, not like human rigging or pistons.
[Note:] I never imagined these props would require such work on them.
Thanks and sorry.
This is basic too and you couldn't upload my .blend?
Not bad! Thanks!
