10 Best 3D Printed Phone Accessories

Your phone is probably the most-used device in your life, and the accessories around it tend to be either overpriced or poorly designed. A 3D printer changes that equation completely. For pennies worth of filament, you can print phone stands, mounts, holders, and gadgets that rival or beat what you would pay fifteen to thirty dollars for at a store.

The key is finding good designs. I have tested dozens of phone accessories over the years, and these ten are the ones that actually stuck around and stayed useful. Every item links to 3DSearch to help you find the best model for your specific phone.

Stands and Docks

1. Adjustable phone stand — A desk stand with an adjustable angle for watching videos, video calls, or using your phone as a secondary display. The best designs have a weighted base and silicone or TPU pads to prevent slipping. Search for phone stands on 3DSearch

2. Charging dock — A combined charging stand that holds your phone, smartwatch, and earbuds case in one compact station. Most designs route the charging cables through internal channels so you only see the devices, not the wires. These make great nightstand accessories. Search on 3DSearch

3. Bedside phone shelf — A small shelf that clips onto your headboard or slides between your mattress and bed frame. Holds your phone at night so you do not have to reach for the nightstand. Search on 3DSearch

Mounts

4. Car vent mount — Clips into your car's air vent and holds your phone securely for navigation. The printed versions work as well as commercial ones and cost almost nothing. Make sure to print in PETG if your car gets hot in summer, as PLA will soften on the dashboard. Search on 3DSearch

5. Bike phone mount — Handlebar mount that holds your phone for cycling navigation or fitness tracking. Print in PETG or nylon for the strength needed to handle vibrations and bumps. Add a silicone band for extra security. Search on 3DSearch

6. Tripod adapter — A clamp that attaches your phone to a standard tripod. Essential for photography, time-lapse, or video recording with your phone. Much more stable than trying to lean your phone against something. Search on 3DSearch

Protection and Style

7. Phone case — Yes, you can 3D print a phone case. TPU (flexible filament) produces cases that are protective, grippy, and completely customizable. Add your name, a pattern, or a logo. The fit depends on finding a model designed for your exact phone model. Search on 3DSearch

8. Card holder attachment — A slim wallet that adheres to the back of your phone or case. Holds two to three cards for minimalist carry. Print in TPU for flexibility or PLA for rigidity. Search on 3DSearch

Audio and Media

9. Passive speaker amplifier — A horn-shaped acoustic amplifier that redirects and amplifies your phone's speaker without any electronics. The sound boost is genuinely noticeable, especially for music and podcasts. Great conversation starter too. Search on 3DSearch

10. Ring light phone mount — A mount that positions your phone in the center of a ring light for better selfies, video calls, and content creation. Some designs include the ring light housing with space for an LED strip. Search on 3DSearch

Material Tips for Phone Accessories

Phone accessories need to be precise because phones have specific dimensions, ports, and button placements. Here is how to get the best results:

• Stands and docks: PLA is fine for desk-bound accessories. Hatchbox PLA gives a clean, consistent finish. Use 0.16 mm or 0.12 mm layer height for a polished look.
• Cases: TPU is the only real option for phone cases. Overture TPU is forgiving to print and produces flexible, durable cases. Print slow (20-30 mm/s) with direct drive or a well-tuned Bowden setup.
• Car and bike mounts: Use PETG for heat resistance and toughness. Overture PETG handles the vibration and temperature changes well.
• Tolerances: Phone accessories need tight tolerances. Print a test piece first to check the fit before committing to a full print. Most good models on Printables and MakerWorld include tolerance notes in the description.

Recommended Filaments

• Hatchbox PLA — Desk accessories, docks, stands
• Overture TPU — Phone cases, flexible mounts, grip pads
• Overture PETG — Car mounts, bike mounts, outdoor accessories
• eSUN PLA+ — Stronger alternative to PLA for mounts that need rigidity

Finding Phone-Specific Models

The challenge with phone accessories is that every phone model has different dimensions. A case designed for an iPhone 15 will not fit an iPhone 16. When searching for models, always include your specific phone model in the search.

3DSearch makes this easy. Search for "iPhone 16 Pro case" or "Samsung S25 car mount" and you will see results from Printables, Thingiverse, MakerWorld, and other platforms all in one place. Check the model description for dimensional accuracy notes and read the comments to see if other users confirmed the fit.

The 3D printing community is great about designing accessories for new phone releases. Within weeks of a new phone launching, you will typically find cases, stands, and mounts on the major platforms. If you are looking for the latest designs and user reviews, Reddit is a good supplementary resource.
