Marble Run 003 Expansion

An extension for the Marble Run 003 kit from Bambu Lab https://makerworld.com/en/models/14265?from=search#profileId-14275.

The shaft is replaced with the gear and the new shaft, these must be glued together after the shaft has been installed otherwise, it cannot be installed again For assistance, there is a square on the shaft and a corresponding recess on the gear

The upper unit is also assembled first and then glued to the tower so that it can rotate easily Perhaps mark the position with a pin A hand clamp would be beneficial to use for securing it It's best not to glue the crank arm to the upper shaft of the upper gear Because this way it can be disassembled and operated electrically again without it rotating along The hand piece is printed in such a way that by removing the supports, a tube remains on the handle If anything is unclear, please contact me or write in the comments And a picture of the finished project would also make me happy🤙

I will then adjust the description

Thank you very much

-----Edit----

In V2, a recess was added so that the gears have better free movement where they mesh

This makes it easier for us Makers to optimize models and fix errors. Because we're all just human😉
