🔹 KEY FEATURES

• Standards-Compliant — built to the 10" mini rack standard; works with DeskPi/GeeekPi 10" shelves, most 3D-printed designs and Jeff Geerling's Project Mini Rack recommendations.

• Stackable — mix and stack any sizes in any order. Bolts included for stacking — no extra hardware needed!

• Built to Last — printed in durable PETG for heat resistance and long-term reliability.

• Flexible Mounting — square rack holes accept cage nuts or Rackstuds (Purple & Duo models). Not compatible with Rackstud Red. Cage nuts and Rackstuds reduce wear and make hardware swaps easier.

• Ready to Use — ships fully assembled. Just add your cage nuts and 10" shelves!

• Made in the USA — designed, printed and assembled in-house by enthusiasts, for enthusiasts.

• Some designs that push the tolerance may need minor adjustments
• DeskPi 0.5U shelves: do NOT fit (insufficient horizontal clearance)
