Summary

This is basically a block with notches to mount a backlight on my bike's new saddle.

I switched to a new saddle - the SQlab 602 M-D active. It has a kind of cushion that allows the saddle to move, but prevents montage of my backlight.

The backlight sits right under the two rods that hold the saddle in place, so I needed a block with the right notches to get some distance.

The notches in the block prevent it from spinning during montage and it fits quiet nicely.

I replaced the original short M5 thumbscrew with a M5 x 40mm DIN 933 screw with hex head plus a nylon washer.
