This is a stackable container. It's based on a nanoblock (which appears to be based on a Lego) flipped upside down. There is currently one interchangeable inside for the block. You could print many of these and stack them.

• Main Files
• b-base.stl the main box part
• b-inside.stl a printable organizer for the inside
• Optional Extras
• b-bottom.stl can be used as a simple bottom block
• b-top.stl a simple top
• Source
• block-v1-0.lwo

Changelog:

• 1/20/2017 Version 1.0
• Added a small notch to the lid so that it wouldn't rotate when nudged

Notes:

• Nanoblocks are in the photo. They are much smaller than Legos.
• In Cura, I have to resize the STL files to 100000% - if your percentage varies from that, check things like Build Plate Adhesion settings, etc.
• If you have a Monoprice Select Mini, you may want to check out the gcode files as reference. Those settings worked great for me. They are based on the cat.gcode and things I've read on the web. If you don't have a MP Mini, you should ignore the gcode files
