Building a 3D Printer Turntable

 

I built this turntable for my Ultimaker 2 3D printer. Why? Because each time I changed the material on it I needed to go from using the interface on the front to dealing with the spool and filament on the back of the machine three times. Minor annoyance, I know, but I had had enough!

You can’t wing this too much or things won’t line up, so I did some careful measurements and aligned things well enough that when I blind screwed in the bottom it worked. There are strategies for doing this with large holes predrilled at a 45 degree offset from square so you can screw them in and see what you’re actually doing, but where’s the sport in that?

Now I’m already regretting not making the top piece a circle or gear pattern so I can motorize this for stylish stop motion photography of timelapse printing, but I think I can add that feature later.

John Park’s Happy Chewbacca Mask is a new guide in the Adafruit learning system

Chewbacca is a lovable Wookie with a distinctive voice, but here’s how to give him a voice transplant and add your own fun sounds to this talking mask.

This guide will show you how to swap out the original sound board for an Audio FX Sound Board loaded up with lots of your favorite sounds. You’ll need a specific mask to follow along exactly, but these principles can be applied to nearly any toy designed to trigger a sound effect. Or, add a speaker and switch to the mix to give a voice to any prop or costume.

Here’s the full video for your viewing pleasure.
