Bittle Robot Storage and Travel Box

Update Post 1:

This update is taken from my thingiverse post (see the link below).

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 want to put additional padding and/or items like sensors. Of course, with the .json and .scad file you can alter these dimensions any way you like!

Note that all sizes are internal measurements and the wall / floor thicknesses are 3 mm.

@DarwinJS asked below what I thought the minimum internal height could be. I speculated that an internal height of 45 mm would work. However, in the event, 45 mm seemed too short and I didn't want to waste print time and filament so I went with 50 mm for my "preferred" size. Perhaps some brave soul, with lots of print time and filament on their hands (or really good measuring tools), can determine the true minimum internal height!

Again, go to my thingiverse post for the files but here are some pictures of my now preferred square corner box.

Original Post:

This little 3D printing project was inspired by a post from @DarwinJS (link) regarding a printable travel case for Bittle. I too have wanted a sturdy "Bittle-sized" box for my robot so here is the simple one that I made.

The box uses the OpenSCAD parametric design approach (see https://openscad.org/ ). I have posted the .stl files and the OpenSCAD files on Thingiverse (https://www.thingiverse.com/thing:6824459). The box bottom is close fitting in the "XY" dimensions but has some extra height to allow for added padding during transport. Also, the box top (lid) fits fairly tightly so it should not come off during transport.

The nice thing about the OpenSCAD parametric design approach is that, with the .scad file and the .json file I supplied, anyone can easily tweak the dimensions to get the exact fit you want.

Hopefully others will find this a useful addition! 😀
