It's a remix of the supportless mudguard bracket designed by emartinelli.
I've added two latches which fits under rear bolts covers.
Mudguard bracket is mounted with stock hardware.
I do not recommend printing that bracket with PLA, it won't last long.
update: I've uploaded new design which is stronger and also now compatible with pro model and suitable for 10 inch tires
