Bow Spring Mouse Cable Bungee
A wired-mouse cable bungee whose compliance comes from a printed bow spring: a 2.4 mm x 12 mm leaf arch bends in the XY plane (along the layer lines, not across them) so the 50 mm guide post springs fore-and-aft and keeps drag off the mouse. The 62 x 30 x 5 mm foot sticks down with a VHB square (the spring rides 1 mm clear of the desk) or bolts down through two 4.5 mm M4 clearance holes; the cable snaps into a 6.4 mm trough 43 mm up through a 4.4 mm pinch and still slides freely. Overall 62 x 73 x 50 mm, about 22 cm3 of plastic.
