Minimized size of a popular aliexpress  bluetooth scale to fit on the drip tray of espressso machines (e.g. Gaggia Classic).

Proceed only if you don't mind the inconvenience of undoing 8 screws to replace the batteries

You will have to trim the tip of the 3 screws holding the pcb, shorten and solder all the cables to fit properly

hardware used:

m3 x 10mm hex socket countersunk head self tapping screw (6pcs)

m4 x 10mm hex socket countersunk head (4pcs)

Split *.step file to objects in slicer. Obviously do not bother printing the pcb and loadcell models. I'd recommend to print the top plate at 100% infill for max rigidity

Final dimensions : width 108mm, depth 102mm, height (with optional recessed 8mmx2.5mm silicone adhesive feet) 22mm
