Online 3d software apps are horrid

[3Dn00b]

So i am building a RPi project, and the system is built but i need a housing for it.
I used SketchUp's online modeling app...with great difficulty and made a somewhat rudimentary design.

Working on making the walls and a screw on lid for it. Minor tweaks here and there. If possible, would anyone be able to print me an acual copy once the design is finished? I would of course pay for materials used.

Any help would be greatly appreciated.
I had hoped to have this built before my dad passed, but unfortunately it didnt go as I had hoped. So completing this is a big deal to me.

the site won't let me upload the .skp file. I did try to zip and rar it, but nothing even tho it is less than max allowed size. If i could email it to someone, or if there is some other way to upload it. Please let me know :/
