CAIBI project benchmark: Hadley Telescope
Prompt version 1.0

Help me build Hadley Telescope using the existing creator project at https://www.printables.com/model/224383-astronomical-telescope-hadley-an-easy-assembly-hig. This is a CAIBI benchmark adaptation of the project build brief, not a claim about how the creator used AI.

Project context:
- A 3D-printable 114/900 mm Newtonian reflector that combines inexpensive commodity optics with printed structure, metal rods and a simple mount.
- Build context: 114 mm diameter, 900 mm focal-length spherical primary mirror; Matching elliptical secondary mirror; 1.25 inch eyepiece route, with suitable low and higher power eyepieces; 3D printed lower cell, centre structure, upper structure, spider, focuser and related hardware; Three long metal rods or the equivalent specified by the chosen imperial or metric variant; Single-family screw and nut hardware matching the original or official metric remix; Springs and adjustment hardware for the primary mirror cell; Adhesive and basic finishing materials; Stable Dobsonian, pipe or other suitable altitude/azimuth mount; Optional shroud or baffle for stray-light control.
- Where AI helps: Interpret the build manual, Help adapt imperial and metric hardware, Explain Newtonian alignment and collimation, Troubleshoot print tolerance and fit, Help plan mount and focuser upgrades.
- Physical work: Print and inspect the structural parts, Source and handle the mirrors, Assemble the optical tube, Build or fit a stable mount, Collimate on the real optics, Observe safely and verify focus.
- Main limitation: It is not just a collection of prints. You still need suitable 114/900 mm optics, a stable mount, careful mirror installation and collimation. The open frame also admits stray light, and the creator gives an explicit warning never to point the unfiltered telescope at the Sun.

Read the source first. Use its published design, files, dimensions and parts as the baseline; do not redesign it unless a missing detail requires a clearly labelled proposal. If you cannot access a source or verify a revision, say so.

Provide one practical build package:
1. Design and files: explain the source design, link the original editable files, and identify missing files or modifications.
2. Parts and fabrication: give quantities, exact variants and compatibility, plus a cutting or printing list where applicable. Preserve source dimensions; flag anything unconfirmed.
3. UK and US purchasing: direct product links, checked dates, stock, pack sizes, taxes, delivery and regional costs. Mark unverifiable details as unknown; do not invent links, prices or availability.
4. Assembly: an ordered guide covering fabrication, fitting, wiring or software as applicable, setup, checks and troubleshooting.
5. Cost and time: separate parts, fabrication, delivery, hands-on time and machine time, with assumptions and exclusions.
6. Function and ease: a test plan for the project's stated purpose, likely difficulties, required skills and any corrections or limitations.

Keep source facts, your proposals and items needing physical verification distinct. An estimate is not a measured build result. Do not claim to have built or tested hardware. Include failed attempts and omissions. If a section does not apply, say why.

Use the source as accessed during this run and record its revision or access date. The prompt is fixed; the linked source can change.
