Shown bellow is an adapter plate I designed and 3D printed for mounting a gas can to the rear seat base without needing to drill any holes. The plate bolts to the four holes normally occupied by the rubber standoffs. The standoffs are in turn pressed into the plate for supporting the gas can. I designed the part in Fusion 360 and printed it in ASA plastic (a UV Resistant polymer intended for use outdoors) on my Prusa MK2 printer. The print is at 5 layers per mm with a 20% honeycomb infill and took about 8 hours and 30 minutes to complete.
