This reminds me of a guy on the Ford Fiesta ST forum who has made a cottage industry from 3D printing and selling small bits for the car to forum members to solve little annoyances. One is a blocker piece to keep items from dropping into a gap around the brake handle, another is a small cup to help retrieve items from a hard-to-access portion of the center console.
What other convenient items can be 3D printed for the CB1100? RLETs in different colors, perhaps? My dream has always been to have someone produce the "female" mounting portions of a Givi Monokey box, so that I can attach them to any box I like and snap it in place on my Monokey rack - a vintage style briefcase, for example.
