The Sim Demon wall mounts come as standard with a 3D printed wall mounting plate.
While the main QR mounting needs to be 3D printed to achieve the complex shapes and to avoid any damage to your QR, the plate that the 3D print bolts to and that attaches to the wall can be Aluminium.
This is an Aluminium replacement for the 3D printed part. Giving some extra strength and great looks. Like all of my Aluminium parts it is very well made and finished. Lightly sandblasted and then anodised black.
The images that show 2 parts are of the 3D printed version next to the Aluminium part so you can see the difference.
