This week's FriDIY item is the classic bead roller coaster (or maze) we probably all had as a little kid. I certainly remember having a blast with these when I was about 4. Now with the Your Wild World Bead Roller Coaster, you can print out your own fully customizable toy! Add as many blocks as you like to this modular toy and go as big as you want! We also provided a set of beads you can print out, but this just scratches the surface of what you can actually use for beads.
We wanted to use filament for the wire, but it's absurdly difficult to manipulate and has very little rigidity. Braided filament was an even worse idea. We settled on 14 gauge picture hanging wire, available at most hardware stores for about $6.00 USD. This is an aluminum single stand wire that's easy to bend by hand, and can be snipped easily with wire cutters.
Go nuts with this print! We want to see the craziest and biggest bead roller coasters you can make!
Check out our blog post on this print:
Print out the connector cubes, and the support rails. Start connecting and building your platform. Go as big or as small as you want.
Bend your 14 gauge wire into position. Once you have everything sorted out and arranged the way you like, we recommend using a strong adhesive to connect the connector cubes and support rails and wire into the blocks. This will ensure the print holds up to the intense rigors of children.
We printed all parts with 10% infill, 2 shells, and low resolution. The cubes should only take about 10 min a piece to print, and the rails are just as fast.
