This model is a universal wall mount bracket. It can be mounted to the wall with up to 4 screws. When attached to the wall, you can insert two cable ties on the wall side to attach something like a power supply or so.
I have placed two sizes on the print plate. One 70x105 and one 105x205 mm. Both can be printed together on one printing plate on the A1 mini or bigger printers.
The two were originally designed for three different power supplies:

• 300W Lenovo Thinkbook
• 135W Lenovo docking station 
• 135W Dell Latitude

In response to user requests, we have also designed a version for 15mm Velcro:
