1U rack mount for a shucked MB8600. Once the case is removed it will fit within the 1U height without issues. Use the original mounting screws to secure the modem board. Printed the LEDs STL in clear PETG. Fasten the parts together with M3 screws.
Printed with supports in the LED window.
The left and right can be modified to hold additional equipment as shown in the pictures.
Designed from the ground up but inspiration came from Loopj’s unshucked design: https://www.printables.com/model/123833-motorola-mb8611-mb8600-mb7621-cable-modem-rack-mou
