Bicycle Rack Light Mount Adapter for straight/vertical tabs

prusaprinters

This quick & dirty mount relocates a rear bike light from the seatpost to the rear of a bike rack to increase visibility. 27.2 cylinder diameter means it works with any light that can attach to a 27.2mm seat post.Designed for a sunlite rack, but useable with any racks that have a single, vertical, rear accessory mounting tab with 1 or more holes (as opposed to racks that have an upside down t shape with 3+ holes). I suppose it can be rotated 90deg. to work with a t shape mount, but there are options available from other designers that work with t shape brackets.Designed for a cygolite hotshot, but works with attachment straps up to ~22.5mm in width and ~4mm thick.-Holes are 5mm diameter, approx 18.8mm C-C. Enlarge with a drill bit if needed.-Short version designed for Cygolite Hotshot-Longer version designed for Cygolite HotrodUse nylock nuts or loctite on bolts to prevent loosening from vibration.If you would like to modify the design, let me know in comments and I can share the Tinkercad project with you. I haven't bothered to re-create this in Onshape, sorry!
