If you want to create your own shape for MMSS, such as a 2x7 or 5x5 it's tricky right now. But using these non-printable designs you can do exactly that. And hopefully less tricky.

Included are six base pieces to build other blocks, and this should be enough to build anything you want:

• outside corner (convex; what is seen on most blocks)
• inside corner (concave; built by me)
• wall connector (for straight parts)
• short wall (connects 1 corner and 1 wall connector)
• long wall (connects 2 wall connectors)
• 1x1 wall (connects 2 corners)

The files are provided individually or all together.

As a proof of concept, I'm including two new blocks built using only these and merging everything together:

• 3x3 square MMSS block
• 1x2 L block

If you're wondering how, the project is on OnShape to see what I did.

The pictured 1x2 L bin is available in my MMSS bin project.

Note: Please let me know if there's any problems with the inside corner piece. OnShape was being difficult with it and it might be off by a hair in the model (but prints perfect).

Revision History:

• 1.0 - Initial version with 4 parts and 3x3 block
• 1.1 - Added 1x1 wall, inside corner, 1x2 L block
