I tired making this project a few times and it would get to the 75% completion and then pegs would come off and / or mess the print.

I printed it, and while the top and bottom parts are fine, the 'screw' for the middle sections is rotated incorrectly so the outer spiral isn't properly aligned. I'll fix it and update here shortly.

That being said, printed in glow-in-the-dark plastic ROCKED.

Finally printed it, and I'm very pleased. In particular, the spiral screws and screw holes work perfectly, so the segments join together smoothly, and with exactly the right rotation so the surface spiral is continuous across the joins. And it prints with no support, making it a very clean print. I just uploaded a photo of a "fat" magic wand, and I'm printing a thinner one as well. Magical fun! =-X

I printed a long wand, and while the top and bottom pieces fit together perfectly, the threads on the middle connectors need to be rotated - when they're screwed together the outer spiral isn't continuous.

Wow ... make sure you dip that in acetone to make it smooth, otherwise it could be very uncomfortable in your ... hand.

The next version will light up! More magic!

Funny how a 3 KB OpenSCAD script can generate an 18 MB STL file. Extruding a circle into a spiral mesh generates a lot of data points, even if the resolution isn't particularly high.
