This is a relatively simple model that is sized for a normal 3M Command Strip on the back and a velcro or zip tie through the centre.
Two models are provided: a horizontal print and a vertical print. The horizontal print will probably hold more weight, but you may have issues with the top overhang (supports should be considered with filaments like PETG). The vertical print takes longer, but should be simpler to print well - depending on your bed adhesion you may need a brim.
There is a hole through the centre sized for an 8G Wood Screw (also known as ~4.2mm, #8 wood screw).
The author marked this model as their own original creation.
