Cut the "Elephant Maze":elephant top out of 1/2" thick HDPE, any color. We used the "light blue HDPE":hdpe from the Inventables store.

Optional: Design your own maze in Easel or use "this one":circlemaze and cut it on the reverse side of the Elephant Maze. No need to cut another through-hole for the marble - the one from the other side will work.

Cut the first set of "Bamboo Base":bambooA parts out of 1/4" thick Bamboo ply from the Inventables store

Cut the second set of "Bamboo Base":bambooB parts out of 1/4" thick Bamboo ply from the Inventables store

Clean up the bamboo parts and interlock them to create the round-bottom base. If the parts fit loosely, add a dab of wood glue to hold everything together.
Place the HDPE top on the bamboo base. We used a "1/2 Stainless Steel ball bearing":bb from McMaster-Carr for our marble.

Create a custom Marble Maze by playing with different materials for the top and bottom. We did a version with a Bamboo Ply top and white .25" ABS base
My maze piece outline cut made it through in some parts but not others. Any thoughts on how I could finish it up?. I'm tempted to tried to knock it out, but am afraid I'll wind up cracking the whole piece. Thanks for any help, and really appreciate you sharing this great project!

Hi Brian, I used tabs on it that should be relatively easy to get through with a sharp X-acto or even a band saw or jigsaw. Is there a way you can share photos? It's hard to picture what you're having a problem with. Thanks!

Thanks for the quick reply. Good news is I'm all set! I just started to give the piece some back and forth pushes to realize I wasn't going to risk cracking it, and from there was able to pop it out pretty quickly.

Very nice. One could recycle HDPE (/2\) (bottle caps, ..) to mold into sheets or directly into parts. The resulting HDPE usually has marbling of colours. http://www.openbuilds.com/resources/how-to-recycle-hdpe-bottles-caps-etc-into-sheets-blocks-to-cnc.170/, YouTube, etc. for more information.

Fantastic! Would love to hear how you made the path for the ball. Also, what is the purpose of the short section of isolated line, and the "J" part next to it?
