I needed some plugs for a panel box and rather than bulky plugs, I used XT60 connectors from my R/C toys.

You can place the XT60 male or female end as needed. I made flat panel mounts and plug housings that can stack as well. This makes a solid-feeling plug setup.

You will need: Plug mount- 2 M3x10mm bolts (I used socket heads. It's what I had.) and 2 M3 locknuts Panel mount holder- 2 M3x10mm bolts and 2 M3 locknuts to hold the XT60 Panel mount backing- 2 M3x10mm + your bulkhead thickness (ex. 10mm+3mm bulkhead =~15mm bolt) bolts and 2 M3 locknuts

If you are stacking them, allow 10mm for each housing; 3 stacked fittings= 30mm bolt

There are two plug mount files. One has arrows pointing in and one has arrows pointing out. This can be a reminder of POWER IN or SIGNAL OUT, etc.

Have fun!
