3D Printable Bracket Generator — Custom Brackets from a Description
SliceFoundry's bracket generator creates custom 3D printable brackets,
mounts, and holders from a text description. Tell the AI what you're mounting,
to what, and where — including hole spacing, screw size, and wall thickness —
and download a printable STL.
This is the right tool when the bracket you need doesn't exist on Thingiverse
or Printables: an unusual hole pattern, a specific cable diameter, a non-
standard mounting surface, or a piece of equipment with no published model.
Types of Brackets You Can Generate
- L-brackets — corner mounts with countersunk screw holes.
- Wall mounts — for cameras, lights, sensors, antennas, monitors.
- Shelf brackets — sized to specific shelf depths and load directions.
- Cable / hose clips — sized to specific cable or tube diameters.
- Equipment holders — controllers, tools, microphones, dashcams.
- Furniture brackets — corner reinforcements, leg attachments, drawer guides.
- Workshop brackets — bench dogs, fixture mounts, jig holders.
How to Describe a Bracket
- What it mounts. Object name + dimensions (e.g. "Raspberry Pi 5", "30mm camera body").
- What it mounts to. Wall, monitor, frame, 3D printer rail, vehicle dash.
- Mounting hole pattern. Number of holes, screw size (M3 / M4 / M5), spacing in millimetres.
- Material clearances. Cable diameter, plug size, gap for ventilation.
- Load direction and weight. A bracket pulled in tension needs more wall thickness than one in compression.
Example Prompt
"Generate an L-bracket that mounts a small camera weighing about 100g to a vertical wall.
The bracket should be 60mm wide, 80mm tall on the vertical face, and 50mm deep on the
horizontal face. Use 4mm walls. Wall side: four countersunk M4 holes in a 40 × 60mm
rectangle. Camera side: a single M5 hole in the centre, 20mm from the front edge."
Tips for Printable Brackets
- Print L-brackets with the long face flat on the bed to avoid weak layer-line failures along the bend.
- Use 4–5 perimeters and 40% infill or higher for load-bearing brackets.
- For PETG / TPU brackets, slightly thicker walls (3.5–4mm) absorb impact without cracking.
- Add fillets to inside corners to reduce stress concentration.
- Test a small section first if you're unsure about hole spacing — easier than wasting filament on a full bracket.
