This 3D printed marble run is the best way to kill time during quarantine

A US man created this 3D-printed marble run that works autonomously after following some tips he found online.

Footage shows an intricate course, designed by Netherlands toy shop Out Of Marbles, that gives marbles multiple different routes depending on the order in which they return to a central distribution hub.

The filmer said: "I enjoy printing kinetic designs, and this one is pretty much the ultimate.

It's like assembling a model from when you were a kid.

Print each piece, trim with a sharp knife and sand as necessary, then put it in the right place adding a dab of glue as needed.

"It gave me something positive to focus on during a difficult time - and judging by the reaction from the video, has also brought a bit of joy to others as well.

"On the days the printer would cooperate, I would print one large piece overnight.

Some days you could get two or three smaller pieces done mixed in with the work-from-home day.

Overall it took about three weeks to print, and three days to assemble.

"There is another design that I have not tried yet.

It uses a double screw mechanism to lift the marbles to the top, sending them down two of the interchangeable puzzle modules.

"The designs are very clever, and there have been more modules being released as time goes on.

I'd like to print the double screw machine next.

After all, we're not done with quarantine yet.

"I've been printing for about three years now.

It is a great hobby and can be quite practical at times to churn out parts for various needs around the house.

"There are several great printers you can get for around $200 and virtually unlimited designs and instructions available online for all skill levels."
