Bonnie Geartop Box

Howdy, wonderful people!

More gears!  Potentially noisy ones, too, if you so desire.  This cog-laden box (with cog-style eyelashes, if you choose to interpret them that way) has a big surrounding gear at the bottom that rotates against a smaller gear at 90 degrees to it that drives a lid open and closed.  Levers attached to the big cog mean you can readily open and close the lid in an annoying and noisy manner!

It's probably easier to demonstrate than describe, so I'll pop a video up on Instagram and link it here shortly.  There'll be a link right under this paragraph.  I'm looking into the future, I tell you.

Now, this would all be quite tricky to print in place in its final, assembled form, which is why it actually prints folded open, ready for assembly, kind of like the way the Planetary Phone Stand does.  The securing bolt prints separately in this case, though, just for the sake of robustness since this one's pretty small in the scheme of things.

Printing Tips

This is an articulated model, so check that your bottom layer is nice and neat, and that you don't have any print issues like stringing or overextrusion that might bind moving parts together.  

As usual, all the angles are designed for straightforward printing, and no supports are required!

Print Dimensions

Zippy Box occupies 135mm x 71mm on the print bed and is 71mm tall.

Further Thoughts

This whole thing is a thinly veiled excuse to play with bevel gears.  I went through a bunch of alternative designs before arriving at this one, including one with four separate lids that moved in unison, but the combined play in all those print-in-place moving parts was just too much for reliable, synchronised movements.

Happy printing!
