Pegboard hollow tray, compatible with 30mm spacing and 6mm hole diameter, extremely material-saving

After getting into 3D printing, I acquired various exquisite small ornaments and toys, and I want to display them all on a pegboard. To better showcase the full appearance of the ornaments, the tray is designed to be very thin and light, using a completely hollowed-out base, requiring only 15g of filament to print!

Note: This model is only compatible with pegboards with a 30mm hole pitch (center-to-center spacing); other specifications are not applicable.
