I made this MFT tray to hold my clamps, a mix of Festool and microjig ones, store my UJK dogs, and to put a few marking tools.
The tray can be printed without supports and I used build plate supports for the nut.
I used four M4x14 machine screws and four nuts to fix it. There is enough clearance to push the M4 nuts in the tray nut. While you can use six screws, only 2 or 4 are plenty enough to maintain the tray fully loaded.
