I just need it to hold a sponge filter in place for my aquarium and need as much surface area of the sponge unobstructed as possible. I am very interested, I have spoke to Sandwell college about half hour ago, and I can go there and print it for the cost of plastic used, but I will have to pop out of work to do so, so I may be going there Monday however not sure yet. I will defiantly be interested in a price please though.

out of interest what file type will I need to get this printed? just a STL file?

Thanks
Mike
