  • Main Body Moved CPU bay from front main body to rear:
    • Added a second bay on opposite side.
    • Unused second bay is an additional "side panel".
    • Can be used to mount an extra 40mm fan, panel mounts, or leave covered with a blank plate.
  • Main Body Zip tie anchors added:
    • Six (6) added to crossbar.
    • Four (4) added to front main body (under MCU pillars).
    • Fifteen (15) added to rear main body:
      • Four (4) under MCU pillars.
      • Six (6) above MCU pillars.
      • Five (5) by PSU wiring cutout.
  • (New) Bottom Panel
    • Removable panels for case underside.
    • Prevents finger-pokey by curious children and dust intrusion (see Completed Requests below).
    • Adds feet to the case.

Additional Improvements

  • Core
    • All core parts now have embossed version numbers to help with intermixing version numbers.
  • Main Body
    • Redesigned intakes and modified exhaust mounts.
    • Easier to print.
    • Made room at base for running wires through to external fans.
  • Base
    • Added a third front air vent.
    • All three front vents how have 40mm fan mounts.
  • CPU Trays
    • New template and tray design
    • Old trays still work.
    • New tray is an easier print with fewer supports needed, can be printed in one of two orientations.

front right render

1. The CPU bay is now part of the rear body.
2. The power supply area has an extra vent in front.
3. 40mm, 80mm, 92mm, and 120mm fans are now supported as lid mounts.

front left render

1. There is a matching CPU bay on the opposite side.
2. Optional Neopixel LEDs are visible behind the front vent.
3. All panels now attach with M3 screws.

render from front and undearneath

New universal power supply mount. The mount is off-center and has a passthrough for power switch wiring.

render from the side and underneath

1. The power supply no longer hangs freely. When installed it adds rigidity to the case.
2. Each front vent has an optional fan mount on the inside.

render from the top right rear without rear or top panels on

1. 20+ zip tie anchors added.
2. The MCU tray now mounts with M3 screws.
3. The rear wiring passthrough no longer exposes the power socket.
4. New support for keystone jacks (unoccupied in the render).

render of the Core of an OmniBox with a Manta MCU mounted

1. Experimental support for the BIGTREETECH Manta M8P (CB1 not pictured).
2. Hex flooring for better ventilation and sturdier build.

render of an OmniBox Core from the rear without any panels installed

1. The two CPU bays are elevated to make room for lower bay tray mounts in unused bays.
2. Optional brass heat set inserts.

render from below showing the bottom panel

The new bottom panel fully encloses the case. It can be printed with holes for airflow or closed to prevent dust intrusion.

render from below showing the bottom panel

1. The new Generic rear panel has two wiring cutouts to let the user run wires from the top, bottom, or both.
2. The Generic panel comes in version with and without a 60mm fan (version with the fan pictured).
