Marble Pump to build a Hubelino Marble Machine

For my godchildren, I developed and 3D-printed a Marblepump. The marble pump is compatible with Lego / Duplo bricks and designed to use with Hubelino marble tracks.

I made a short Video, where you can get a first impression. https://youtu.be/UdZP1RB9AnA

As explained in the Video, I designed two versions. The differences in the feeding of the marble to the marble pump.

Version 1 (feeding with generic Hubelino track)

Auger V1
Pump housing V1
Version 2 (feeding with optimized marble track)

Auger V2
Pump housing V2
Feeding slope V2
Common parts (version 1 and 2)

I recommend that you first print the following sample brick to tune in the printer settings for a perfect fit to the generic bricks.

Enjoy!
