well first off. No. Just laying hot plastic isnt gonna get as much of a detailed shap like you want. You really need a vac table. All you need is to make the table, drill a hole in it and attach a vacuum to it. If you go to www.studiocreations.com and click on their how to section, they show you how to build one thoroughly.
Now if you are wanting something that is clear, then PETG is what you need. It forms like styrene but is clear. The thing is you can use your kitchen oven for the heat source, I do that myself when I'm forming things. So thats pretty much it.
