Modular Shelf for presenting goods. The joints have a tolerance of 1.0 mm or .5 mm. You can connect as many middle parts to the shelf as you need.

If you have .4 mm nozzle I suggest you to try print file with .5 mm tolerance first. Same base file can be used with both versions.

I printed with brim and 15% infill (and plate supports for the middle part). 

By default, all files are in the best possible print position.
