One generic, ATX / ITX / MATX sized IO Shield / Motherboard backplate for a 1U SuperMicro server chassis.
My own design, this has been tweaked through several iterations for a good fit :)
3D printed in white PETG, for a durable finish and long life (PETG is more flexible and less brittle than PLA, also PLA degrades over time - not great for this!). High accuracy, printed with a 0.4mm or 0.6mm nozzle on an optimised pre-set (for the right balance of strength and flexibility vs easy cutting), using a BambuLab machine.
Let me know as a note on checkout if you'd like it in black instead - and, when you order 4 or more I can provide in alternative colours too - drop me a message with your choice and I can let you know if I have it in stock!
