Great design marble machine

This marble machine is very well designed to be easy to print and put together. Absolutely love the way it looks printed with eSun silk copper and eSun marble.

Jouissif !

Quel bonheur de retomber un peu en enfance à 73 ans et de faire rire de plaisir les petits-enfants émerveillés de ce que leur grand-pére sait faire. Grand-pére qui ne leur a pas parlé de Luka bien sûr ..................

This is a lot of fun!

Really enjoyed making this. Not only is it just a pleasure to print, assemble, and's a great way to engage and teach kids of all ages about everything from electric motors to gravity. Not hard to print, though it does take some time. (Hint: before printing, make sure you calibrate your extrusion multiplier using Luka's excellent "Test Fit" calibration model.)

I guess my bottom line is: If you *think* you'd enjoy these machines, you will enjoy these machines.
