This is my first design to share.

It's an effects pedalboard designed to allow for expansion so that it's just the right size for all your pedals.  I'm currently using 2 A sections on my desk as a mini pedalboard.

The cross pieces are the same width as 3m Dual Lock 1 inch wide (for example SJ3550)

To connect the pieces together use the connection cubes and zip ties.

I printed mine with the following settings and it's holding up great:

• draft (.3mm) 
• PETG
• 15% infill

Hope this design suits your needs as well as it has mine.

Cheers,

Rick
