Customizable standard taper joint Buchner funnel

The included STL is for 29mm 1:10 (standard taper) conical joint. Soluble supports are preferred.

EDIT:

Remove hexaholes from .scad if you want the better, finer and bridging-compatible (prints w/o supports) slicer-generated mesh to appear (set infill to rectilinear 50% and no solid top and bottom layers)
