You might be better off finding a thin PVC tube or something similar. You can plug the ends after cutting it to the right legnth- ReBoot has a very crisp design for everything, very basic pure geometric shapes. The more you can capture that, the tighter your end product will look! I'm sure you can get industrious if you root around a little, and still keep a tight budget.
Otherwise, you've gotten your basic components down well! Fully support this project, I have at least one of the action figures myself (1st Gen Bob).
Will you make any attachments for the various Glitch-tools? Can't wait to see how it goes!
