Kệ đựng thẻ bài Baseball

A simple storage rack for holding baseball/trading cards (~64mm x 89mm). Racks have a slight draft angle on the sides to improve rigidity and allow for easier stacking. Reliefs at ends for easier insertion/removal access. Intended for 'mass storage'  and not 'ideal' protection.

I have printed copies from PLA and PETG, a 10% infill is fine since the majority of the part is just perimeters anyway (using 0.6 nozzle), but I haven't tested higher fills for more robust stacking.

For my application I don't have a need for lids, but if it would be beneficial, please feel free to reach out and I could toss an update together.
