this is my second entry to the Technology Digital Design Competition: Universal 5.25-inch Drive Enclosure – Stackable 3D Print by Blærøv.

Bring new life and portability to your old 5.25-inch drives. This clean, stackable enclosure fits standard optical drives and hot-swap bays using M3 side mounts, and it connects via a SATA–USB adapter cable for true plug-and-play use.

Compatibility Standard 5.25" optical drives (Blu-ray/DVD/CD) and 5.25" hot-swap bays with M3 side screws.

Stacking Top recesses for feet interlock between modules for stability.

Fastening Four lateral M3 screws into the device (typical 5.25" pattern).

Print time ≈ 6–10 h depending on layer height and speed.

Printed weight ≈ 180–260 g depending on material/infill.

• Material: PLA+ or PETG (PETG/ABS for higher heat).

• Nozzle & layer: 0.4 mm nozzle; 0.20 mm layer (quality) or 0.28 mm (fast).

• Infill: 15–25% (Gyroid/Grid). Walls: 3; Top/Bottom: 5 layers.

• Orientation: open face up — prints without supports.

• Cooling: 60–100% PLA; 30–50% PETG.

• Clearances: sized for standard 5.25" devices; widen lateral holes +0.2 mm if needed.

• Post-process: deburr side holes / lightly sand edges.

• Real 5.25" standard: lateral M3 mounts align with OEM hardware — no adapters.

• Portable: pair with a SATA–USB adapter to use internal devices externally.

• Scalable: interlocking feet let you build stable towers with the same footprint.

• Print-friendly: support-free orientation saves time and material.

• Serviceable: slide-in fit and common screws enable quick swaps.

1) Clean-up: remove any stringing/burrs with fine sandpaper.

2) Feet: place rubber bumpers into the top recesses (optional bottom feet for the lowest module).

3) Insert: slide the 5.25" device in from the front until side holes align.

4) Fasten: use four M3×6–8 mm screws through the lateral holes.

5) Connect: attach power/data. For portability, use a SATA–USB adapter cable.

6) Stack: place modules one over another; recesses help prevent sliding and vibration.

• Leave 10–15 mm of rear clearance for cables and airflow; do not block device vents.

• For heavy metal hot-swap bays, use PETG/ABS and ≥25% infill.

• Avoid >55 °C with PLA (risk of warping).

• If screws feel tight, widen side holes +0.3 mm or use M3 washers.

Device won’t fit: Verify internal width at 100% scale; remove internal burrs.

Screw holes don’t align: Nudge device 1–2 mm; enlarge lateral hole +0.3 mm if needed.

Vibration when reading discs: Use taller feet / thin foam under the base; rubber-washered screws.

Stack slides: Use higher-friction feet (TPU or 70A rubber).

Adjustable Phone Mount for Xbox Game Controller is a Blaerov project that is kept alive by the community. If you want to help it continue to grow, consider acquiring a Support Token! The tokens are 3D printed and represent a token donation that allows me to invest in more free designs for everyone.

Token Symbolic value Equiv. in 10 MXN coins link

¢50 0.50 USD 1 coin 

$1 1.00 USD 2 coins

$5 5.00 USD 10 coins 

$10 10.00 USD 20 coins 

Every token I acquire translates into real coins that will fill my BiggyBank 3D model. The goal is to collect 4,000 coins (≈ 40 kg) to upgrade my gear and spend more time designing!

 How to get Tokens

• Visit my page on Creality Cloud and search for "Support Tokens – Blaerov".

• Download the . STL corresponding to the desired value.
