The indicator housings on my  2002 BMW GS650 bike with very sun damaged and had cracked letting water in. So naturally, I took one off, drew it in Inventor and printed myself a full new set of 4 which I then smoothed with acetone.  Again sadly I don't have pictures of the final product anymore and I didn't even bother checking what it would have cost me to buy a new set.
