Isochronous curve are amazing. No matter the point where you drop the ball. takes the same ammount of time to the center

I love marbles and this is such a fun experiment. It would be amazing to see your makes. You could share it with kids in your area and take it to your science class or school... Im sure they will love it
Use ball bearings from 6-8mm diameter.
A tautochrone or isochrone curve (from Greek prefixes tauto- meaning same or iso- equal, and chrono time) is the curve for which the time taken by an object sliding without friction in uniform gravity to its lowest point is independent of its starting point on the curve. The curve is a cycloid, and the time is equal to π times the square root of the radius (of the circle which generates the cycloid) over the acceleration of gravity. The tautochrone curve is related to the brachistochrone curve, which is also a cycloid.
Bases and curves are completely simmetrical except fot the name and logo on one base. If you want to add your own logo/name, just add it to the clean base side and print two.
Prints without supports. The included gcodes for the mk3 and MINI are sliced with the Prusament filament profile, 20% rectilinear alligned infill. You can print the whole set in one go with the mk3s, if you want, or in two on the MINI.
