Also use it in ChatGPT or Claude
3D Printer on Demand is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
Add it to ChatGPT
- 1
Open ChatGPT settings
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
- 2
Turn on developer mode
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
- 3
Create the connector
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
- 4
Use it in a chat
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
Add it to Claude
- 1
Open Claude settings
In Claude, open Settings, then Connectors.

get_print_quoteUse this when someone asks how much it costs to 3D print a part, or wants a quote to have a 3D model (an STL, 3MF, STEP or OBJ file) printed and shipped by 3D Printer on Demand. It reads the attached file, checks that it can be printed, saves the quote, and returns the estimate wupdate_print_quoteUse this when someone wants a different quantity or color on a quote 3D Printer on Demand already gave them. It takes that quote's private link and the new quantity, works out the estimate again from the file saved with the quote, saves it, and returns the new estimate with a newlist_materialsUse this when someone asks which plastics 3D Printer on Demand prints, which colors each comes in, which material suits a job, or which materials are quoted by a person. It returns each material with what it is for, what it is not advised for, its colors and how it is quoted, pluget_service_detailsUse this when someone asks how 3D Printer on Demand works: lead time, shipping, how long a quote is held, accepted file types, the largest part, the items we refuse to print, or where to upload a file, request a review or get in touch. It returns these facts as our website publischeck_printabilityUse this when someone attaches an STL, 3MF, STEP or OBJ file and wants to know whether it will 3D print well: size, walls, mesh problems and what to change. It reads the file, runs the same automatic design checks as our website, and stores nothing. It gives no quote. When no filget_design_guidanceUse this when someone asks how to design a part for FDM 3D printing: wall thickness, tolerances, hole clearances, overhangs and supports, orientation, infill, bosses, ribs, snap fits, threaded inserts, dimensional accuracy, published material figures, or printing compared with morecommend_materialUse this when someone wants help choosing which of our plastics suits a part, from where it will be used: indoor or outdoor, heat, impact, flexing, chemicals, looks and material cost. It returns the materials we offer that fit, best match first, the reasons in plain words, and thcompare_print_vs_moldingUse this when someone wants to compare 3D printing with injection molding for a quantity, using their own numbers: quantity, printed unit cost, tooling cost and molded unit cost. It returns the totals for each, the crossover quantity on those numbers, and the published range withsize_hole_or_toleranceUse this when someone asks what clearance or hole size to draw for a printed fit: a sliding part, a bolt or pin through a hole, two printed parts that mate, a press fit, or a snap fit. It returns published starting clearances and hole guidance, each with its source, and how to tequote_from_linkUse this when someone shares a link to a 3D model, such as a model page on Thingiverse or Printables or a direct link to an STL, 3MF, STEP or OBJ file, and wants a quote to have it printed and shipped by 3D Printer on Demand. It reads the model's licence where the site publishes get_order_statusUse this when someone who ordered from 3D Printer on Demand asks where their order is or what state it is in.

It does not show the shreorder_from_orderUse this when someone wants the same parts again from an earlier 3D Printer on Demand order. It takes the private order link from their order email, works out a new estimate for each part from the files saved with that order, and returns a private link to review the parts and ordcombine_quotesUse this when someone has two or more quotes from 3D Printer on Demand in this chat and wants to order the parts together. It takes the private quote links, saves one quote that holds all the parts, and returns its private link with one combined total and one shipping charge, nexRecent checks
