What can you build with PSU Enclosure Studio?
Any ATX, SFX or SFX-L power supply, or one you measure, from 60–250 mm wide. Makers build:
- A bench supply with fixed 12 V, 5 V and 3.3 V outputs on binding posts.
- A variable supply around an XY-SK120 or DPS module, with its own posts and fuse.
- A USB charging station with a switch and an LED on the front.
- A small SFX supply for a crowded bench, lying flat with a wide front.
- A front panel alone, printed as a drilling template for a case of your own.
How do you design the enclosure, step by step?
Five steps take you from the power supply to the pieces to print. The enclosure beside them follows every change, assembled or laid out for printing.
1. Measure your power supply
Pick ATX, SFX or SFX-L, or Custom and type the size you measured, lying flat. Set the fit around it, whether it stands upright (a tall front) or lies flat (a wide front), and its screw pattern, so the back bezel lines up with its screw holes.
Step 1: the power supply the case is built around. 2. Lay out the front panel
Choose a variable module or none, the rails and their labels, the ground, fuses, binding posts and components such as USB chargers, switches and LEDs. The tool places them in columns and shows the panel flat; drag the panel preview to nudge an item, and it tells you what does not fit.
Step 2: the module, the outputs and the labels. 3. Shape the back bezel
The back bezel frames the power supply's own back, so its switch, socket and fan stay open. Set the lip that holds it and the brand engraved in its border.
Step 3: the bezel around the PSU's back. 4. Choose how the frame joins
Rails at the corners, printed rods, metal rods or a base hold the two panels apart; a sleeve can close the wiring space. Pick heat-set inserts, screws and nuts or self-tapping screws, the panels' thickness and how deep the wiring space is, or let Fit to components size it.
Step 4: what holds the panels together. 5. Pick the pieces and download
Choose the pieces to print, 3MF or STL, and one file or one per piece. The parts list counts the screws with their lengths, the inserts or nuts, the posts, fuse holders and components to buy. Downloads need a free NabiMakes account.
Step 5: the pieces and the parts list.

Which print settings work best for the enclosure?
Every piece prints as it lies in the file, without supports: the panels flat (face up with the marks on top, unless something on their inside needs the bed), the joins standing up. The layer height is a starting point for your slicer; the thinnest wall is the one the printer checks hold each filament to. With inlays, a printer with several filaments prints the marks in their own colour.
| Filament | Layer height to start | Thinnest wall | Supports | Notes |
|---|---|---|---|---|
| PLA | 0.2 mm | 0.8 mm | None | Fine for the panels; keep the supply's vents clear, PLA softens near hot parts. |
| PETG | 0.2 mm | 0.8 mm | None | The better choice near the supply's heat; tougher joins and corners. |
Tips for an enclosure that goes together well
- Measure the power supply with calipers, lying flat, and keep the fit at 0.5 mm or more: printed walls are never quite straight.
- Print the front panel first: it is quick, and you can try the module, posts and switches in it before the rest.
- Let Fit to components set the wiring depth, so the deepest part behind the panel has room.
- Keep each pair of binding posts at least 16 mm apart, so banana plugs and spade terminals fit side by side.
- Before you print, check it on the view's bar: Dimensions shows its size, Measure the distance between two points, Section cuts it open and Layers steps through it as your printer will.
What if the module will not clip in, or a part is left off?
- The variable module will not clip into the panel
- Set the panel's clip range to the module's clips, or turn on the clip notches or the recess that thins the panel around the cut-out.
- A component is left off the panel
- The panel has no room for it: add extra panel room in the PSU step, remove another component, or pick a smaller one; the Front step names what was left off and why.
- The back bezel's holes miss the PSU's screws
- Check the screw pattern in the PSU step, and turn it half a turn if your supply's fan side is the other way up.
- A panel is wider than your printer's bed
- Choose your printer in the checks, and lower the border or the extra room; the checks name the piece that does not fit.
Is PSU Enclosure Studio free?
Designing and previewing are free for everyone, and the default enclosure downloads free with a free account. A design that uses a Pro feature needs the one-time unlock.
