I love the Fietsvaas of Wilco and they have project files in theirs so I moved some lines about in Fusion 360 and added strength to the hook/elastic receiver with a fillet.

Please take care with surface adhesion, because the base is thin, the top can move. I have included a screenshot of what worked for me after 1 failed attempt.

For printing I turned down acceleration by more than 2/3, to reduce torque on the model in moves.
