The Hammond Manufacturing 1590 series is perhaps the most successful and influential low-cost, small enclosure series to be produced. These have been cloned by many global manufacturers, but the original Hammond Manufacturing boxes made in Canada are of the highest quality and can also be obtained pre-painted. These small aluminum enclosures are tough, reliable, and very popular for amature radio and music related electronics projects, such as electric guitar effect "stomp boxes".
I decided to make some template projects from these enclosures as I do design my own boutique guitar pedals and almost always use these 1590 series boxes as the enclosures. Having the 2-D assembly drawing and 3D STEP models makes it much easier to place the components such as potentiometers (a.k.a. pots), LEDs, Displays, and Foot Switches on the PCB, as well as plan the PCB's shape to fit precisely in the enclosure.
I will follow up with a 90° tilted version of this template in future, as sometimes it's better to have a small PCB mounted perpendicular to the enclosure's back (lid) or front (case). I have specified that the lid is actually the bottom in this template, because 99.9% of stompboxes use the lid as the bottom of the device, so as to hide the enclosure screws and also it looks better with the slight fluting of the enclosure.
I hope you find this useful. I sure do!
