This mount was specifically designed to fit the handlebar bracket for the Ducati Monster. The center of the design has a mount that is compatible with quadlock.
One M5 insert is required for the centre hole, and 4 x washers (1 for each bolt) is recommended (see pictures).
I have the Ducati Monster 659 2014 model. The official part number for the handlebar bracket is 36010991A.
This print should be compatible with the following Ducati models provided they have the above part fitted:
NOTE: It's recommended that this be printed using a strong durable filament, as well as considering using a high percentage infill. The reason being - this will fit over the existing bracket. The bracket bolts are fed through the printed mount (on top), through the bracket (middle), into the steering. See the pictures attached. Use at your own risk :D I've had absolutely no issues using this so far.
The author remixed this model.
I required the center of the original, and used it for my model.
