Update: Based on suggestions from other makers I have added a 3rd version with trim tabs on the base and above the gear mechanism to stabilize the pedals while printing. If you don't mind a little trimming after printing give the "Trim Tab" version a try. Hopefully this will be a much easier print.
Update: Added a 2nd version with a thicker tapered support for the heart. Some people have had issues with the heart stem failing during the print. If you run into this issue or don't mind a heaver support please give the "Thick Heart Support" version a try.
Re-mix of my original blooming flower toy with a heart center for valentines day.
Free Base from Collar
Use a flat blade screwdriver to free the base from the rotating collar. Gently work around the full perimeter to lift the collar from the base. After freeing the collar, free the threads by twisting back and forth on the collar while holding the base. After working working through a few complete cycles open and closed the box with loosen up and rotate freely.
Trim Tab version
If printing the trim tab version you will need to cut all of the tabs on the top and bottom to free the pedals before freeing the collar above.
