• inspired by the great marble machine from tulio ([https://www.thingiverse.com/thing:1385312](https://www.thingiverse.com/thing:1385312))
• I wanted to create my own marble machine using a pack of 6mm diameter steels balls (airsoft ammunition with the same diameter should work too)
• You will need around 50 steel balls to make it work!
• I wanted to try a different method of elevating the balls/marbles. I created a system where they are pushed into the vertical shaft one by one using a kind of geared wheel
• this pushwheel is connected to a wormgear to have it self-locked and with a high torque to push the tower of balls inside the elevating shaft
• the marble machine is seprated into the base, with the elevating mechanism and the elevating shaft and the marble track itself with the nozzle on top
• It is a modular concept, to be able to have different track options with only one base
• the parts will need a little bit of glue during assembly, but don´t glue track and nozzle if you plan to keep it modular
• I plan to release more track designs in the future
• all parts are designed to print without any support

• parts you need to print:
  1x base_bottom
  1x base_top
  1x pushwheel
  1x drivegear
  1x wormgear
  1x handle
  2x washer
  1x bushing
  1x nozzle
  1x track(4 revolutions) or track_slower (5 revolutions)
