Reconstruction of the photographed bracket: rounded open frame, inclined side plates, crossbar, four internal tabs and two coaxial lugs, one of which is slotted. Without a scale reference, the assumed overall size is 28 × 36,5 × 21 mm, for a nominal shaft of 4,6 mm; the main dimensions are adjustable. Dimensions: 28 × 37 × 21 mm. Printing tips: Print in the supplied orientation, with the frame flat on z=0. Use localised supports beneath the overhanging lugs and, if necessary, inside the horizontal bores. Use a 0,4 mm nozzle, layers of 0,16 to 0,20 mm, 5 perimeters and 60 to 100 % infill. Prefer ASA or a PA suitable for the operating temperature; avoid PLA in the passenger compartment. The holes include a diametral compensation of +0,3 mm: check the fit on a first print.
