Guitar Pedal Enclosure V3.0

20241008 - Update: added version with no holes.

After 8 years and many other prints and designs I'm am coming back to the beginning. Back in 2015 before I had even finished building my first 3d printer I started doing some basic 3d design work. The first model I published was Guitar Pedal Enclosure:

There were definitely some issues with the design and I never got around to correcting them, until now.

I redesigned this from scratch in fusion 360 and once again worked from the dimensions of a 1590b. Box is 112mm x 62mm x 31mm. Lid latches with force-fit joints but can be removed with flat-head screwdriver.

If you print the box face down you shouldn't need supports.

But what about noise without the metal box? Definitely possible, but if you ground everything with star ground type of pattern you should be OK. There are even some production pedals that have plastic enclosures. Danelectro had a whole series with plastic boxes for example, Grilled Cheese https://reverb.com/item/110499-danelectro-dj-10-grilled-cheese

Most PCB designs use ground planes on each layer which will provide some protection. Another possible solution could be conductive filament.

I built a woolly mammoth clone on tagboard https://tagboardeffects.blogspot.com/2012/10/zvex-woolly-mammoth-cut-down-version.html and did not observe extra noise from the pedal.
