At a glance

Rack: 19", 3U tall
Material: PETG, which holds its shape near warm gear where PLA softens
Not included: Rack screws. Use whatever your rack takes.
Made: Printed to order in Illinois

⚠️ Before you order:

Check yours is an M4 or newer. The 2010 to 2023 Mac Mini is a different chassis and has its own four bay mount in my shop.

Fits four Apple Mac Minis in one 19" rack, 3U. The mount is two printed halves that bolt together, each holding two Mac Minis stacked, so a four node cluster takes one bracket instead of four separate mounts.

FITS

Apple Mac Mini M6
Apple Mac Mini M5 Pro
Apple Mac Mini M4
Apple Mac Mini M4 Pro

These all share the same chassis, so any mix of four fits.

WHAT YOU GET

Both printed halves, plus the hardware that joins them at the centre seam. The two are a matched set and bolt to each other.
Rack screws are not included. Use whatever your rack takes.

MATERIAL
3D printed in PETG, not PLA. Four Mac Minis working in one bracket put out real heat and real weight, and PETG holds its shape where PLA would start to soften. The centre seam is built with a deeper dovetail and thicker joint blocks than my single mounts, because it carries all four.

Single, double and triple 19" versions of this mount, and a 10" mini rack version, are also listed in my shop. 💬 For any custom design requests please message me.

Every 19" mount bolts together before it goes in the rack. Which guide fits depends on how this one is built:

Either way: rack screws are not included, the oval slots take M6 and #12-24, and the device goes in last.
