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.
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.
