DON'T PUT THE ROPE TOO HIGH IN CASE OF BREAKAGE !!!!! I carefully positioned the zip line at a child-friendly height, less than one and a half meters, to ensure they would need to bend their knees to avoid touching the ground. Thorough testing has proven its safety with children weighing under 20 kilograms. I also tested it with my own 75-kilogram body weight, but unfortunately, it failed to generate enough speed for me to slide along. This design was modified from a pre-existing model found on Thingiverse (https://www.thingiverse.com/thing:363800). To improve performance and durability, I added emplacements for two 608 bearings to reduce friction and reinforce the axis. Additional enhancements include increasing the pulley's diameter by 2 millimeters to accommodate the bearings' thickness and adding a 1-millimeter margin on each side to account for rope wear. The axis was reduced to 10 millimeters in diameter to fit a 10-millimeter handle (I used an aluminum rod, approximately 200 millimeters long). Requirements: * 2 x 608 bearings * 3 M4 screws * 1 aluminum rod, approximately 200 millimeters
