Arduino Uno Keyhole Bumper Tray
A screw-down tray for the Arduino Uno R3/R4 footprint (68.6 x 53.3 mm board) with four 7 mm standoffs on the factory hole pattern, 2.6 mm self-tap bores for M3 screws, a 12 mm bumper rim on three sides and the USB/jack end left open. Two #8 keyholes 30 mm apart hang it on a wall or screw it flat, and a 19 mm cable-tie apron with four 3.5 mm slots strain-relieves the USB and barrel cords.
Dupont 1-6 Pin Housing Sort Tray
A 123 x 94 x 22 mm bench tray with 12 bins for 2.54 mm Dupont/JST-style housings. Bin widths grow with pin count, from 11 mm for 1-pin to 26 mm for 6-pin. The front row holds male housings (marked with round dimples) and the middle row holds female housings (marked with square dimples). Two 25 mm troughs at the back take loose crimp pins, so you don't have to dig through the kit bag for a 3-pin female mid-build. Every bin has a 45° scoop ramp at the front to make small parts easy to pick out.
