hello,
for those who have saddle tail light with rubber band and plastic hook which is broken like me, this support fits this tail light and is directly mounted on the saddle rail. the main advantage is for the MTB with frame shock (in general, once on the bike, the tail light is hidden by the wheel or bike rack.

• Only 2 zip tie to fix the support on the saddle,
• 1 screw (the screwn already in place with the tail ight).
  print it with ''flat'' face on the bed. no need of support. fan is set at 70% to corectly print the overhang (zip tie).
  I added another version with angle to compensate the seat tube angle (depending on frame geometry).
  update May 27th: saddle support for 2 x tail llight.
