Bath Fan Motor Retrofit Slotted Adapter Plate
A 150 x 80 mm ribbed adapter plate for mounting a universal replacement bath-fan motor in the original fan housing when the bolt holes don't line up. It has 4.5 mm slots for #8 / M4 screws: four radial motor slots cover 44–76 mm across on X and 44–64 mm on Y, and two end slots reach housing holes 96–140 mm apart. A 34 mm centre bore clears the shaft and hub, and 10 mm edge ribs keep it stiff.
Headboard Slotted Bolt Adapter Plate
A ribbed 160 x 60 mm adapter plate for a headboard whose bolt holes don't line up with the bed frame bracket. It has four 8.6 mm slots, 50 mm long, in two rows 32 mm apart, and takes 5/16 in or M8 headboard bolts set anywhere from 30 to 130 mm apart. The flat lands around the slots fit a 22 mm washer, and the plate's 9 mm stiffening ribs face away from the headboard.
Bidet Attachment Slotted Hinge Bolt Plate
A stiff 180 x 44 x 4 mm plate that goes between the bowl and a bidet attachment in place of the flimsy bundled bracket. Its two 12 mm slots take 3/8 in or M10 seat hinge bolts at any spacing from 125 to 155 mm, which covers the standard 5.5 in (140 mm) spacing with room either side. There are 5 mm tick notches on the rear edge for centring the plate, and a cut-out window to save material.
Universal Smoke Detector Box Adapter Plate
A 130 mm ceiling adapter ring, 6 mm thick, for fitting a new smoke or CO detector to an old electrical box. The counterbored box slots sit on a diameter and run from 66 to 94 mm hole spacing, which covers 3 in round, single-gang (83 mm) and 4 in octagon (89 mm) boxes. Four radial M4 slots for the detector have a captive-nut track underneath and reach 64–116 mm screw spacing, and a 50 mm hole in the middle lets the wiring through.
FPV Stack 30.5 To 20 mm Deck
A 46 mm square, 3.2 mm thick adapter deck that bolts to a frame drilled for the 30.5 x 30.5 mm M3 standoff pattern and carries a 20 x 20 mm M2 flight-controller / ESC stack on four 7 mm posts, lifting it 6.5 mm clear of solder pads and motor wires. A 16 mm centre window passes the battery and ESC leads, two 12 x 3 mm slots take zip ties, and 7 mm scallops in each side edge route wires off the plate; M3 holes are 3.4 mm and M2 bores 2.4 mm so the screws actually drop through.
