Air filter "box" for dual Weber 40 IDF

Could´nt find a filter box that fit my FIAT X1/9 so I made my own. I printed in ABS to be able to handle the heat. I have only tested this so if you try the same design test and be careful so that you don't get any fire in the engine room. ABS don't handle petrol well but it seems to work for this application. I have used a 3" (75mm) high air filter with an outer diameter of 15" (600mm). Large V8 paper filter. The fit for the filter element is on the loose side. The 3 clamps works for me but could be tighter. I will try with a slightly different design. Support needed (ptobably) only for the Cranc case ventilation pipe.
