Order custom 3D-printed parts from templates or your own files. Design plates, brackets, spacers and boxes with exact dimensions, choose materials and colors, see live pricing, and checkout on plyparts.com. Also search and print ready-made models from Printables and Poly Haven.

Example request: "I need a custom L-bracket 50mm by 40mm with 3mm thickness and two mounting holes, printed in black PLA."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use ply 3D Printing to help me. It is a free service with an MCP server at https://www.plyparts.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- make_part: Build, check and price a custom 3D-printed part from exact sizes (mm): plate with holes, L-bracket, spacer/standoff, washer, or box with lid. Shows the part in 3D with its price and an Order button. Sizes left out use sensible defaults. Use again with new sizes or options when th
- price_file: Price the customer's 3D file (STL, 3MF, STEP or OBJ) and show it in ply's card. Without a file, shows the card with an upload button (with sourceUrl: the model page to download it from). In ChatGPT, pass a file the customer attached. Pass `path` (from an earlier result) to change
- price_model_link: Price a 3D model from its page link and show it in ply's card. Printables: ply fetches the file itself if the license allows printing it for sale (CC0, CC BY, CC BY-SA, GPL, Commercial Use…) and credits the designer; other licenses are declined with the reason. Poly Haven (CC0 de
- find_models: Search for ready-made 3D models ply may print and sell: Printables (open or commercial-use licenses only; non-commercial models are left out) and Poly Haven (CC0 decor, props and figures, scaled to fit). Returns titles, designers, licenses and page links.
- recommend_material: Run ply's material advisor ("Help me choose" on plyparts.com) for a part: it may ask up to 2 questions about how the part is used, then recommends a process, material, color and strength. Give either the part's ply `path` (a file) or its template and sizes (a built part).
- order_part: Put a part into a ply cart and get the link to finish the order on plyparts.com (shipping, payment, engineer review). Nothing is charged here. For a built part pass the same template, sizes and options; for a file pass its path and options.
- list_materials: The materials, colors and strength levels ply prints custom parts in, with what each material is good for.
