Saddle bag/rear light holder for Bicycle seat

Remixed from https://www.printables.com/model/117517-saddle-bagrear-dynamo-light-holder-for-bicycles

In the remix besides the altered rail angle mounting for my Selle saddle I put 2 more slots for zip ties as well as a rework with a separate adaptor boss to mount my rear light This boss is fitted to the saddle mount with a 5mm hex cap screw but you will need to tap a thread into the hole provided in the boss.  Feel free to design your adaptor to suit your chosen light. (My remix of the saddle mount was 1st designed for a different light that mounted directly see last photo)

I recommend the use of PETG or ABS/ASA for durability. The STL is oriented to print upside down. Supports should not be needed.

Updated 3rd July 2022 : Includes a variant for a Selle Royal Road Mountain Bike Saddle
