This is a mount, attached to a 5015 radial fan, to hold the Bowden tube and the cables. Two small tie-wraps hold the tube and cables in place while M3 screws fasten the mount to the radial fan. While this is specifically designed for the HyperCube Evolution, it might fit other printers featuring 5015 radial fans.
I've printed the part in black ColorFabb PETG at 0.2 mm layer height. The part is designed to be stiff and of low weight.
