About this 3D model

This is the Rambone slingshot, designed by the crazy german, Jörg Sprave. https://www.youtube.com/watch?v=MlG3P_wf-6E He shared a STL file of the model, but it has holes in it and some other inperfections. Also its very high res. I cleaned up the holes, optimized the model a bit and made it a true solid. You can get the original file here: http://www.simple-shot.com/pages/build-your-own-rambone-slingshot I have not printed this yet, bit I'm fairly sure it will print nice. Heres how to attach the elastic band: http://www.simple-shot.com/pages/tutorials-diy If you print it, please share your results.
