This compact shelf is designed for effortless 3D printing, featuring an integrated under-shelf specifically tailored to accommodate 2.5" HDD drives. The design incorporates a recess for inserting 3M nuts, which, while not mandatory, significantly enhances the shelf's strength and stability.

For added durability and stability, a higher infill is recommended. Additionally, affixing rubber pads beneath the legs would provide extra grip and protection for surfaces.

I hope to add some more add-ons , using the decorative holes on top to hold some additional attachments. Or feel free to add some more things.
