This custom designed velocity stacks fit on vintage solex carburetors. The top part can be taken off in order to put in some kind of grid (I cut up some old sieve) to keep debries out of the intake manifold. A custom die to shape and cut the grid is also included in the files, i strongly recommend using it, since it gives the grid it's ideal shape that prevents it from being sucked in.
I further recommend to either use a Resin printer or to at least smoothen the inside surface so the airflow isn't disturbed by the layer-lines.
Obviously PLA is NOT recommended for this print, at least not if you intend to actually use it, since temperatures inside an engine bay tend to rise above ~60°C on a hot summer day.
In case you have questions, don't hesitate to ask.
