Had a bit of tinkering time so came up with two possible ideas...
idea 1 http://www.flickr.com/photos/oilyanator/5331019058/
Made with 2 modified telescopes and 2 modified large teeth.
idea 2 http://www.flickr.com/photos/oilyanator/5331019058/
(sorry for the bad image quality)
Made with lightsaber that will be cut to a better size, 2 hooks which the stud will be cut off from and the same 2 teeth.
The only problem with these designs is that it is very hard to attach a vent to, any ideas on that?
(a vent is something that plastic is poured through.)
Have no favourite out of these 2 and would appreciate opinions. thank you!
