The top shell is part of a Air Wick Freshmatic automatic air freshener. I think I found the correct model, but the only place I could find a good photo of it was on ebay: http://www.ebay.com/itm/Air-Wick-Freshmatic-Automatic-Air-Freshener-Dispenser-White-Fresh-Waters-Refill-/301527240198

Great project, currently printing. What did you use for the white cover/house? Is there a file available?

Hi,

Your BOM on the instructions has a mistake. The metal pipe dimensions should be 13.5cm and 3.5cm, 8mm diameter I assume ?

you're right, thanks!

Could you post the source files?

Sure but all the files are in ".fun" format. I think you can open them only with cubify invent

Scaled Rubber bands sentry gun barrel

Hi and thank you! I'm glad you like the project. Unfortunately the shell is not a printable part, is a piece of the case of an air wick freshener

Cheers mate. Your a champ!

I'm having problems scaling the barrel. Could you please uploaded an already scaled model. Thanks.

Printing one of these out. Unfortunately by printrbot SM only has ~6x6x6 build volume and the base bottom is slightly too big. Are you able to provide the source so I can tweak it a bit? Also the 'shell' seems to be missing (and also too big for my printer).

Thanks!

Edit: Remixed version of the base with rounded 'legs' now up; fits inside 6x6 build plate.
