Expandable Moog Profile Eurorack Case

Overview

This is a modular and expandable eurorack case with the slanted Moog profile.

There's left and right sections in 30hp and 45hp widths that can be combined into a 60hp, 75hp and 90hp cases. I plan to add a middle section in different sizes to be able to make more widths.

The 45hp left section has a 4hp rear module slot to fit a power module without taking space in the rack. I recommend using a 4ms Power Row, this way you can daisy chain them if you build a 2 or 3 tier rack.

The side plate holes match the ones in Moog cases. If you have any of the Moog studio synths and want to expand into eurorack, you can reuse the wooden side plates of your Mother-32, Subharmonicon or DFAM. Otherwise you can print the included sideplate files.

The bottom of the case has two recesses that fit standard 10mm or 12,7mm 3M rubber feet.

Parts needed

• Square nuts
• M3x10 screws (four per joint)
• M3.5x12 screws (four per side plate)
• Moog wooden side plate and metal spacer (there's an stl version included if you prefer to print it)

Assembly

The left and right parts slide into each other and are fixed using M3x10 flathead screws (the ones with the conic head) and square nuts. The flathead screws sit flush on the case. The joint is rock solid and has no play at all.

For the eurorack rails, use the same M3 square nuts and you're good to go.

The side plates use M3.5x12 screws. The holes aren't threaded. They will self tap as you screw those in. Be careful to not over tighten.

Coming soon

I plan to support more sections and combinations. This is what I have in mind:

• A standalone 40hp section with a 4hp rear module slot
• 84hp → Combining a 30hp left, a 24hp center and 30hp right sections
• 104hp → Combining a 45hp left, a 24hp center and a 45hp right sections
• 104hp →Combining a 30hp left, a 30hp and 24hp center sections, and a 30hp right

I'm also planning two and three tier stands.

Printer settings

• 0,4 nozzle and 0,2 layer height
• 100m/s speed for the outer wall (there's many sharp corners and it's best to avoid bulging corners)
• No support: Plate it vertically with the side plate side facing the printer's plate)
• 10% gyroid infill
• Make sure your printer is well calibrated. The joint assembly has a .2mm tolerance. You might want to test your settings with the joint alone before printing a larger section.
