Our new How I Made It series takes us inside the projects that have inspired our designers, shoppers, and makers. Last week, designer and Shapie Mitchell Jetten’s miniature roller coasters got lots of attention from the community. I asked him to share how they came to be. Leave a comment if you’re interested in having us feature your latest project.
Back in 2014, I got the idea to start 3D printing rides from a game I used to love, RollerCoaster Tycoon.
I had no idea how to paint this, and not having too much money in my pocket, I decided to make a small version in Full Color Sandstone.
I’m sure many people will still remember these rides and their iconic entrances and exits.
A couple of years ago I decided to go a bit bigger. I decided to 3D print a Boomerang Rollercoaster, which cost around $300.
Definitely worth every penny, as it was a staggering 60cm long.
This was all great, but I didn’t expect that anyone would be willing to spend $350 on a 3D printed roller coaster.
Rescaling this roller coaster wouldn’t work; the rails would be too thin to print.
I designed around five or six rollercoasters back in 2014, but, with a Boomerang already coming out at $350, there was no way the others would be close to affordable.
This plan went in the fridge till last month.
It made me think about the issue: why couldn’t I rescale the coaster and sell it for a lot cheaper?
The tracks where too thin, so the the only option was to get rid of the detailed track, make a tube, and hope it would still have a coaster feeling.
As everything is done by using splines, changes were made easily to the track.
The test print of the second prototype arrived just days later.
Right away, I noticed that some supports had to be a bit thicker due to their length, but that wasn’t really a problem and it was fixed just minutes after detecting the problems.
And the results:
