This is a remix of two models, "Valve Index hook” and “Valve Index Controller Desk Mount Hook (Ikea Trotten, Any 20mm Desk)”.
I have combined the two so a Valve Index can be hung from a desk without the need for screws or adhesive.
The desk mount component is designed for a 20mm thick desk but will work on slimmer desks, especially if used with padding like adhesive pads.
It will require support, I found using auto with support filament used for the support interface to work best.
