Modular NAS HDD/SSD Bracket with TPU Sliders & Dampeners

Overview: This is a modular 3D printable HDD/SSD bracket designed for NAS servers and DIY storage setups. The frame is printed in PLA, while flexible TPU sliders hold drives securely in place and reduce vibrations. TPU dampeners can also be added for further shock absorption.

The modular design allows you to attach brackets on one or more sides, enabling compatibility with different drive sizes and external enclosures. Works with both 3.5” HDDs and 2.5” HDDs/SSDs. I specifically designed and tested this as part of my Raspberry Pi 5 NAS build using this https://www.printables.com/model/742926-raspberry-pi-5-case Raspberry Pi 5 case.

Features:

Modular assembly — add/remove sides depending on the drive size.

TPU sliders — grip the drive and keep it from moving.

TPU dampeners — reduce vibrations and noise.

Works with external HDDs or SSDs.

Robust PLA frame construction.

Compatible with Raspberry Pi 5 NAS builds.
