1590 Hammond Enclosure Collection

This collection includes the most common enclosure sizes used in DIY guitar effect pedals.
Stompbox builders will recognize these formats. 
The models are dimensionally matched to classic Hammond and Hammond-clone aluminum enclosures.

These models are ideal for prototyping, layout testing, switch/jack placement, or fully 3D-printed pedal builds.
You can print them in PLA for prototyping, but I’d recommend using PETG or ABS for the actual build.
