While the original "v0.10" box with round corners is suitable for storage, it is not optimal for travel. The Bittle robot, when collapsed, has a rectangular shape so a box with square corners is better for carrying around or packing in your luggage. Such a box provides a tighter fit to hold the robot more securely (little "rattling"). I also found that the original box top was unnecessarily tall.

I have therefore added a "v0.11" version with square corners and a shorter box top. The box bottom comes in 3 heights (Short = 50 mm, Medium = 60 mm, Tall=70 mm). My preferred size is the the Short since it very closely fits the Bittle robot. This is the size I have photographed (with the red box top).

The other sizes are useful if you…

@DarwinJS, on my Bittle, neglecting the wires that I added to access the ports on the Hat Extension, I estimate a Bottom internal height of about 45 mm (plus whatever you want to add for padding below or above the robot) might work for your situation. Still I recommend you take some careful measurements on your Bittle. If this measurement is accurate, I would also reduce the Top internal height to about half of the bottom height (so about 22 mm). This is partly for esthetics and partially to make the lid a bit easier to remove.

BTW, this was just a quick first design. The current box is fine for storage but for transport, I think more optimization is needed. For example, I am not happy with how the front corners act as pressure points for the front leg "knee" joints.

Regardless of the design, I think padding / blocking is needed to keep Bittle from rattling around in the box and thereby getting damaged during transport.

<Update: The new design with square corners and tighter tolerances means little or no padding / blocking is needed to keep Bittle from rattling around!>

When you plan to transport your Bittle in some box/case, will you hand carry it or will you put into checked luggage (and all the extra shaking that implies)? Also, do you have any specific length, width or height restrictions or is the desire to merely "keep the box" as small as possible? Any further input from you and others in the forum on this topic would be appreciated.
