3D Printed Cosplay Props

What you need

The build order

1. 1 — Source or model the file

   Marketplaces such as Cults3D, MyMiniFactory, Printables and Thingiverse carry thousands of character props. Check the licence before you print anything you plan to sell, and check the model is watertight before slicing.

2. 2 — Scale to your body, not the file

   Most props are uploaded at display scale. Measure your forearm, head or reach and scale the file accordingly. Print a 20mm test slice of the contact area before committing 40 hours of filament.

3. 3 — Cut and key the parts

   Slice large props into bed-sized chunks with alignment pins or dovetails. A keyed joint glues straight and survives a con floor; a flat butt-joint will snap in a bag.

4. 4 — Print for strength, not speed

   Three to four perimeters and 15-20% infill for anything load-bearing. Orient the part so layer lines run across the stress axis — a blade printed flat snaps at the tang.

5. 5 — Fill, sand, prime, repeat

   Filler primer, sand, spot-fill, prime again. Two or three cycles turns a visibly striped print into a smooth surface. This stage takes longer than the print did — plan for it.

6. 6 — Paint and mount

   Metallics, washes and clear coat, then add internal reinforcement (a wooden dowel or carbon rod for long props) and any hand grips, magnets or straps.
