Pure Fun Project!!

This is a remake of the gravitrax scoop, it will move the marble up by 4cm with "slow" speed, 3.5cm will give it more velocity.

This is print in place!
no support or brim needed.
Set the flat long size on the bed in your slicer
10% infill, works fine.
Print in PLA works perfect,

once printed trim and rotate the hinges until they rotate freely

put two marbles in the "top" slots of the catapult arm (carefully: the wall of those are thin and tolerance is made to keep them tight)
then rotate the arm in vertical position and lock it by pressing the trigger and you are ready for the ride!
experiment with your makes, and see! (and let me know).

feel free to comment, and to like it, I'd love to get feedback and see your makes!
