Less Material CD/DVD Storage

Update: after a few revisions I made this version which I'm a lot happier with, took down material used by 3g more now its just 6g of material to print and print time is down to 1 hr 20mins, although print speed is not my goal. I might stop here or I might explore other ideas to drop material usage even further. I have printed designs that only used 4g but they were unusably bad.

Planned on printing quite a few of these with limited materials so decided to just randomly poke holes on it to make it take less material. CURA says it takes 9g, used to take 13g. I'll probably make another one that takes even less material and is less ugly later.
