Parametric Pouch — Magnetic Closure, TPU Fold-and-Glue, Customizable Size | Fusion 360 Parameters Included

A fully parametric pouch that folds flat and assembles with glue — no sewing, no hardware beyond 2 magnets. Customize width, height, depth, magnet size, and belt loop position directly in Fusion 360's parameter window to fit tools, pencils, small parts, or anything similar.

Prints flat, folds into shape, and closes with a magnetic flap.

Customization parameters:

• Width, height, depth — default 40x120x20mm shown in photos

• Magnet diameter and width — default 10mm diameter, 3mm thickness neodymium

• Belt loop cutout height and offset — optional, can be removed entirely

Deviating significantly from the default proportions may cause unexpected folding or fit results — test with default values first before customizing heavily.

Two seam variants included:

• Normal seam

• Inverted seam — folds slightly easier, recommended if you're having trouble with the fold lines

Assembly:
Prints unfolded as a flat pattern. Fold along the seam lines and glue closed. Loctite super glue works well for this — in testing, TPU was actually easier to bond than PLA or PETG. Add support under the magnet tab area — this is the one spot that needs it.

Removing the belt loop cutout:
Open the Fusion 360 source file and suppress Extrude18 — the standalone extrude feature not contained within a group.

Hardware Required:

• 2x neodymium magnet, 10mm diameter x 3mm thickness (size customizable via parameters)

Print Settings:

• Material: TPU or similar flexible filament strongly recommended. Not tested with rigid filaments — results may not fold correctly

• Walls: 3

• Top/Bottom layers: 4 each

• Infill: Effectively 100% due to 1mm wall thickness on the sides — no separate infill setting needed

• Supports: Yes — magnet tab area only
