Mission success! First batch (Well, only had time for two...) came out perfect!
Its TPU, so not exactly rubber, but flexible and somewhat grippy. Good enough for a Quadra!
They are Snow White colored, which is good and bad. The originals in ads looks very white, however the set of originals I have are light gray. So not exactly sure on how they should be colored? The edges to the "teeth" are a little messy, still working on them. They fit perfectly in my 700 and stay in place.
Photo time!

Trash, thank you for your input. I'd be happy to try anything you'd want! I don't have either of those, so would just need measurements.
Unsure of what I would price these at, but obviously everyone here that's a member will get Them cheaper! Will also be listed on eBay.
Thinking $10 for four for members? Maybe we can work out a bundle deal if you need more than a set? eBay listed ones will probably be $15 ish... I think it was MJ who made the first batch, and was charging around that, so I'll keep it around there.
Anyways, will be making lots more tonight and tomorrow, and if anyone is interested in purchasing some, PM me! I'll respond as soon as possible.
