These are melon plants and not picked fruits. Scaling only works creatively. Placement would work by using a soil block and planting the corresponding fruit. Gravity should be deactivated for this, otherwise it will be problematic. At least until the function for placing objects comes into play. It shouldn't take too long.
Until then, please use THIS HERE
No mention or other obligations are necessary. Just enjoy & have fun
Inspired by your creation I tried to create a stall of my own just to have alternatives but couldn't workout how you got the soil in the creates or pots, now I know. Thank you for sharing.
