Five Prosthetics You Can Easily 3D Print for Halloween

Hello again, children! How have you been? 

Halloween is almost here, and if you’re tired of the same store‑bought masks and props, a 3D printer can help you create custom, small-scale prosthetics that make any costume stand out. These pieces are wearable, quick to print, and give your look a professional, polished edge without breaking the bank. Checks all boxes for me. Let’s get into it: 

1. Partial Arm or Hand Prosthetics

A robotic finger shell, skeletal glove, or partial arm cover instantly elevates a costume. Printed in metallic or matte filament and maybe painted with details, these pieces add dramatic flair while staying lightweight and wearable.

2. Eye or Facial Gear

A monocle-style eye piece, partial cyber mask, or steampunk lens frame can transform half your face. Print a base shell and optionally add tinted acrylic or paint for effect. EZ.

3. Claws or Talon Extensions

Print small finger or shoe extensions to give the appearance of claws or monster talons (especially if you’re going as that one Doja Cat red glittery fit – iykyk someone pls wear this). Lightweight PLA or TPU works well and lets you wear them comfortably for hours.

4. Small Mechanical or Decorative Augmentations

Think LED-housing forearm pieces, ribcage add-ons, or partial robotic joints. These small attachments make your costume appear modified or enhanced without a full suit. Whatever your creative, twisted little mind can cook up, your printer will serve (grrrah) it to you.

5. Ear or Horn Prosthetics

We don’t appreciate “one size fits all” here. From subtle fae ears to small demon horns, 3D printing lets you create pieces that actually fit your head. These prosthetics are easy to attach with spirit gum or elastic straps and look far better than generic rubber versions. Or you can get creative and inventive, either way, your 3D printer has your back.

Final Thoughts

3D printing gives you complete control over Halloween accessories, letting you customize size, color, and style. With these small prosthetics, you can create a unique costume that stands out from generic store-bought options. Pick your favorite files, print, paint, and assemble—your friends will think you spent hours on a professional design. 

QUICK PSA: You may have noticed, that I didn’t give you links from 3Dvinci – that’s because not only do I not want to only write these blogs to advertise our products, since there are many products and creators out there that also deserve your attention, but I also noticed that we haven’t really discussed where else you can find printable files. So here’s a few, and if you want more in-depth info on some of these websites – comment and let me know!

That’s a wrap! Go chase after people with your TPU claws (for legal reasons – I am KIDDING. I would never encourage violence ever. Unless slaying a fit counts…). Scram.
