DrMaker3D: custom 3D printing, figures, cookie cutters and gifts

Custom 3D print price examples

print_price_examples

Read-onlyIdempotent

Real prices from the DrMaker3D instant quote for three reference parts (a 2 in clip or knob, a 4 in bracket, a 6 in enclosure) in each material, at Standard quality, 20% infill, one copy, before shipping. Use it to give a person a ballpark; the exact price comes from uploading their file at the instant quote page, or from a quote request. Also lists the upfront prices for a figure made from a person's photo or AI picture (4, 6 or 8 in tall, one color or full color, one figure or two on one base, keychains, sets; free shipping in the contiguous U.S. included; standing figures a range, keychains fixed; full color is up to 6 colors, extra colors cost more), ordered on its own page, and the prices of cake toppers, name keychains and photo lithophanes, each designed on its own page.

A4/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The annotations already establish that this is a safe, read-only, idempotent lookup. The description adds useful scope and caveats such as 'before shipping,' ranges for standing figures, fixed keychain pricing, and extra color costs, but it does not describe the return format or currency. With the safety profile already covered by annotations, this is adequate but not rich.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The core purpose is front-loaded, and the usage boundary is clear. However, the final sentence is a dense run-on packed with product-variant details, making the description longer and harder to scan than necessary.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only price-reference tool with one optional parameter and no output schema, the description explains what is covered and when exact pricing is required. It is nearly complete, though it omits currency and does not describe the returned price format.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and the schema fully documents the optional material parameter. The description only implies material filtering by saying prices are listed 'in each material,' so it adds little beyond the schema baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description specifies a concrete verb and resource: it lists real reference prices from DrMaker3D's instant quote, including which parts and configurations are covered. It also distinguishes the tool from exact quoting by explaining that ballpark prices come from this tool while exact prices require file upload or a quote request.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives explicit usage guidance: use this to provide a ballpark, and use the instant quote page or quote request for exact pricing. The boundary between this reference-pricing tool and exact-quote workflows is clear.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
