TMNT Plastic Ramps

Quoted from zizzlemeplease:
lexan-polycarbonate would be a good choice for vaccuforming, could be clear and tough to break.

Lexan is very difficult to vacuum form. Acrylic and PETG are the other choices of which PETG is the best. I'm making a clear PETG ramp for my High Speed right now. PETG is 7 times as durable as Acrylic and for comparison, Lexan is 17 times more durable than acrylic...but Lexan does not form well. PETG is the best and forms very well. Attached is a photo of a test pull for HS to check fit. Decided to revamp the mold to eliminate the need for the cover. Should form that on in the next day or two.

I've tried to pull polycarbonate, but at thicknesses of .100 to .125 it just does not form well and can easily bubble. Expect it would perform better at thinner thickness. PETG at .100 pulls very nicely and with good detail. I have experimented with a lot of different vacuum formers. First tried the typical home setup with a shop vac but ended up using a strong vacuum pump. Typical vacuum can pull about 4"-5" of mercury in a vacuum tube (How they measure vacuum strength). With my vacuum pump I can pull better than 24" of mercury.

How many separate ramps are there are TMNT?
