[sdiy] M3-threaded PCB mounts with solder tails?

Hello,

I recently purchased an Intellijel 7U Performance Case, and it’s nearly perfect.

Who makes the M3-threaded PCB mounting brackets that are soldered (in three places) on the MIDI JACKS rev003 board? I think I need to buy some of these. Are they a custom part? … or are they available some place like Mouser, Jameco, or Digi-Key?


I’m in the process of designing a replacement for the MIDI board that would have active MIDI circuits. It’s intended to interface with a Euro module of my design that provides 5 V and serial data on a single header, without the optoisolator or current loop conversion. I could build an adaptor with the needed circuit somewhere else in the case, but it seems like the best option is to design a replacement PCB that will fit exactly where the MIDI JACKS rev003 does now. So, I’ve measured the placements for the MIDI jacks, USB jack, and screw holes. I already have the USB and MIDI jacks, so all I need are those metal brackets that solder via four pins each to the PCB and have M3 threaded holes in the right position to align with the 7U case.

My design has jumpers to switch MIDI THRU between a buffered version of MIDI IN or a second MIDI OUT. In my case, the extra bandwidth of a second MIDI OUT will probably end up being necessary.

I plan to keep the USB wired to the 10-pin header in the same way for compatibility with any existing (1U?) modules that might use USB, but will leave the MIDI pins unconnected since I’m taking them over.

p.s. I’ve already designed and built a 1U module that is a buffered 4-channel 1/8” to balanced circuit that connects to the existing Audio Jacks Board v2 via the 10-pin header. I really appreciate that both the Tip and Ring for all four jacks are brought to that one header. I ended up making all four jacks into outputs, and that was simple because the Audio Jacks Board is passive - so the direction isn’t baked in to the hardware. Of course, the labels painted on the case are no longer totally correct, but this is a personal modification for a 4-voice modular synth with individual balanced voice outputs.
