One pair of 2x Drive Rails for an HP Z420 / Z440 Workstation - may work with other models too but haven't tested!

An alternative to the original HP trays, I've tweaked these for a forgiving fit and to maximise clearance at the ports side. Unlike the originals, these do require 4 screws per drive, but any HDD sized screws should work fine.

3D printed in black PETG, for the required flexibility, as well as a durable finish and long life (PLA prints degrade and soften over time - not great for this!). High accuracy, printed with a 0.4mm or 0.6mm nozzle on a strength optimised pre-set, using a BambuLab machine.

Order 4 or more pairs and I can provide in alternative colours - drop me a message with your choice and I can let you know if I have it in stock!
