Introduction: Bento Ball
Bento (弁当 bentō) is a single-portion takeout or home-packed meal common in Japanese cuisine. Sometimes served in a box, with a fox, or kangaroo.
Containers range from mass produced (disposable) to hand crafted lacquerware. Somewhere in the middle there are 3D printed ones to be had.
What goes inside... food, marbles, electronics, etc. - whatever you like!
Step 1: 3D Printz
Fire-up your printer... we're about to print some great balls with fire. Use white, black, blue, red, green, yellow, purple, or whatever colors suit your fancy.
The hemispheres will take a while to print and will require support material. Set one to print before you go to bed and again the next morning before you're off to work for the day. Remaining parts print fairly quickly.
This archive contains all the files you need.
Step 2: Assembly
Other than your plastic parts, you'll need a few bits of hardware. If you like shiny things, go for the stainless steel socket cap screws. Old school... you can always choose classic black. One of the following will do.
And, you'll need a couple of these to secure the button.
Oh! ...and the spring from a clicky-click pen - sandwich that between the button and the mounting plate.
Step 3: Single-portion Takeout
Now to the hard part... what are you going to fill it with?
We have a be nice policy.
