About this 3D model

Hi Everyone! One of my friends ask me to create a Wall Mount for his Bicycles. He just want to use a wooden Rod and one Screw per Holder. I Print the Holder in ABS with 4 Walls and > 30% Infill. After that you need a Round rod in 40mm. I use oak for his holders. The Rod is glued in the Plastic holder and get additionaly secured with 3 Screws. To be sure what the holder is not moving around i Addad a 8mm Metal rod in the back of the wooden Rod, but that is up to you. The Metal rod is an additional security for the complete holder.
