Available in 2 different flavours, this miniature marble machine makes a perfect desktop distraction. Crank the handle round manually or connect it up to the teeny motor and watch the marbles go round automagically. 

The kit is made from 3mm laser mdf. It is basic slot and tab construction which provides a tight friction fit on most of the joints. A small amount of wood glue (not supplied) is required for 2-3 of the joints. The machine comes with 8x 10mm ball bearings for normal operation. The assembled machine is 100mm x100mm x100mm in size

The motorised variant of the kit comes with motor, battery box, switch and additional fixings to hold it all together. You will need a soldering iron to wire it all up. Batteries are not included due to shipping restrictions.
