Little Duckis Little Roller Coaster

Welcome To Little Duckis Little Roller Coaster! Lil ducki saw a fabulous roller coaster for little duckies on the internet and wanted its own! So here it is! It includes stunning two turns (WOW!) and a highspeed lane never seen before (HUH!) - at least not seen by lil ducki ;-) A short clip is avail here: https://youtu.be/aND3CrYCoLA <iframe width="560" height="315" src="https://www.youtube.com/embed/aND3CrYCoLA" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> Lil duckis incarnation here is the modified very fine model from Karan Arora https://www.thingiverse.com/thing:663362 provided under a CC license, thank you very much. The modification includes a flat bottom with an optional M3 screw placement for additional weight and some scaling to fit to the ladder. About the gears and the movement there is probably some help needed by some sanding and rasping to make the stuff work without too much friction, but by avoiding too much looseness too (especially making the ladder hang or drop in to hefty jumps). If the gears move smooth before adding the ladder, everything should work fine. But anyway, it is about fun - for lil ducki and you ;-) The parts marked with optional are for the geared motor driven fun where the motor with gear was some no name product from my fund, with no idea where it was ordered... But a search about ``micro motor gear'' should give a hint about some alike models. The optional big gear has some spares for M5 screws forced in and some screws at the side going down when the ladder goes up can help as a counterweight. Well, this was a suggestion of lil ducki, nice idea - but it must not help :) And as a print helper there is a simple 12 mm disc, which can be placed at small areas on the bed before slicing to help around adhesion trouble and can be easily cut off after printing. I hope the parts provided will fit good enough without too much fiddeling to provide happy rides! Have fun!
