Use the Benchy skill "Plan a print project". 1. Read https://benchy.world/skills/plan-a-print-project/files?path=SKILL.md and follow it. If you support skills, save it as one. 2. Save https://benchy.world/skills/plan-a-print-project/files?path=BENCHY.md as BENCHY.md at the root of my project, and keep it current as we work. 3. Then start on this: Use this skill to plan a wall bracket for a 12 mm dowel, printed in PETG on a Bambu A1. Ask me for anything you need to measure.
What you’ll need
- Idea, sketch, photo or a part to measure
A written description works too.
- Useful dimensions; calipers if you have them
Agent skill · Version 0.1.1 · MIT license
What you can work toward
- Ask for the measurements, printer, material and environment before anything is modelled
- Keep measured, given and open values apart instead of inventing a dimension
- Choose how many parts to print and which face goes on the plate, with the reason
- Name the files to produce and the checks that decide when the part is done

--- name: plan-a-print-project description: >- Plan a 3D-printed object: purpose, measured dimensions, printer, material, output files, and acceptance checks. Use before modelling, when the brief is a sketch, a photo, a sentence, or a broken part. title: Plan a print project date: 2026-09-26 author: Benchy tags: [3d-printing, planning, fdm, skill] license: MIT metadata: version: "0.1.1" schemaVersion: 2 surface: "Any agent · no account needed" --- # Plan a print project Produce a one-page plan before modelling. Record missing measurements, printer limits, material requirements, and unresolved choices. ## Ask before you plan Get answers to these. Where the user does not know, write the question into the plan as open; never invent a measurement. 1. **What it does.** What the object holds, joins, protects or replaces, and what happens if it breaks. If a failure could hurt someone (load-bearing, child use, food contact, heat or electricity), say so plainly and recommend a qualified review. This skill does not certify safety. 2. **Size and fit.** The overall dimensions in millimetres, and every dimension that must mate with something else (a screw, a shelf, another part), with its tolerance. Ask for calipers readings over estimates. 3. **Printer.** Make and model, build volume, nozzle diameter, and whether it has an enclosure or multi-material. 4. **Material.** What the user has, and the required stiffness, flexibility, temperature range, and outdoor exposure. Check the filament manufacturer's specifications and printer requirements before recommending a material. 5. **Where it lives.** Indoors or outdoors, temperature range, sunlight, water. ## Write the plan Return a short document with these sections, in this order: - **Brief:** one paragraph: the object, its job, and who uses it. - **Constraints:** a table of dimensions, tolerances, printer and material, each marked _measured_, _given_ or _open_. - **Approach:** how many parts, and why. Split a part when it is larger than the build volume, when a split removes most of the supports, or when layer direction would put the load across layers instead of along them. - **Print orientation:** for each part, which face sits on the plate and where supports are likely. - **Files to produce:** an editable source (for example a `.blend` or CAD file), a print file (`.3mf` for units and parts, or `.stl` with units recorded separately), and a short notes file. Slicer project settings depend on the application that saves the 3MF. - **Done when:** the checks that decide completion, such as a test print of the critical fit, measured dimensions within tolerance, and the part doing its job for a stated time. - **Open questions:** everything still marked _open_. ## Hand off After modelling, use `prep-a-model-in-blender` to check the mesh and `print-prep` for slicing. Keep the plan beside the source and print files. ## What this skill does not do It does not model, slice, or print. It does not decide that a part is safe. It reports what was measured and what was assumed, and keeps the two apart.
