A Better GraviTrax Ramp Insert (for both Drops and Jumps)

thingiverse

The GraviTrax "Catch" insert that comes with GraviTrax starter sets does not work well. It has a flat section at the exit, and marbles often stall on this section. It is unbelievable that Ravensburger did not design the Catch insert with a slope over its entire surface.This improved GraviTrax Drop Ramp insert fixes the problem. It is sloped over its entire surface. No matter where the marble drops, it will roll out of the insert.There are 2 primary designs. The "Better Ramp" is similar in design to the GraviTrax Catch insert. The "Best Ramp" has raised front walls which better capture the marble when it bounces from a drop.UPDATE: The ramps have been updated with a jump ramp in back so they can also be used as marble jump ramps with a magnetic cannon.For an even better drop ramp that you can buy, see Coogelbahn.de's marble catcher at https://www.coogelbahn-shop.de/en/gravitrax-3d-print/25-coogelfaenger.htmlFor the smoothest finish, print in .12mm height increments. But the insert works just fine when printed in .20mm height increments as well.There are 2 versions of the each ramp. The normal version of each design has a small wedge on the back to firmly grip the insert into the GraviTrax base tile. If this is too tight, use the "no wedge" version which should fit without friction.
