Purpose:
As the title says, with this holder you can mount a Philips Hue Hub under a desk or similar.
The bottom is open and allows cable connection. The front allows to push the button and the view to the signal lights.
I printed it upside down without support. Depending on your printer, you may need support under the mid section of the circle in the center.
Used screws: 2x Torx/SPAX 3,5x25mm
Update from 2021-12-21:
I've added an additional version with flanges at the sides instead of the back, and for each version a variant with a shorter flange for shorter screws.
Used print parameter:
Material: PLA
Resolution: 0,2mm
Infill: 25%
Brim: no
Support: no
