Marble Genius funnel top support

thingiverse

Just whipping up something to print so I came up with this design. It fits over the funnel piece in the set, supporting pieces above it. The center is hollow and aligned to drop through the hole in the funnel. It's a one-way attachment as the three "ears" aren't evenly spaced. Update: July 6, 2019 Found that some marbles were hitting the spoke nearest the entrance. Added an extra 0.5mm clearance for the v10 file.
