This is a pin I designed to go in place of the fumbly and inconvenient allen screw that retains the pillion seat on the Triumph Street Scrambler / Scrambler 900. No modifications to the bike or seat needed, this just slides in place and is retained by the seat cover. The part of the pin that fits into the brass threaded insert is a tight fit, expect to do some deburring and shaving to get your fit perfect. I printed this with PETG filament, 15 lines to make it solid. Flat side to the print bed, tree support only needed under the narrow part of the pin. In my testing it works really well, you can have the seat off in seconds and back on just as quickly, with no tools and no risk of scratching the fender with tools or a steel screw.
