Dual controllers stand

I wanted to obtain a vertical support for two universal controllers, taking up as little space as possible and above all stable.

Having found nothing that suited me, I designed this part which can accommodate two controllers, regardless of the brand.

For more stability I created 4 locations underneath that can accommodate anti-slip pads.
For my part, these are standard 8mm diameter skates found at LIDL.
Finally, still for the sake of stability, the part is printed with a filling density of 15% apart from the base which is filled to 80% in order to lower the center of gravity.

I printed mine in PETG but it won't be a problem with any other material.
