Fan and cable-chain bracket

After trying you a lot of different fan/cooling solutions, i did designed my own bracket.
This cooling solution is extremely simple and effective, and i usually have my fan set at 50% speed, so i do not cool the print too much.
This bracket is also working as a cable-chain holder for my Bowden setup.
Its ment to be used with a 50mm Radial Cooling Fan, the fan is mounted with a M4 machinescrew directly in to the plastic with no nut.

The other end of my setup, the nema-17 motor bracket, can be found here https://www.thingiverse.com/thing:3520269


The extremely well designed chain i have used for this project, is stolen here from bernbout https://www.thingiverse.com/thing:1732556


EDIT:
This chain have a new and more sturdy design now, (iteration2)
