TMT Telescope 1/250 Model | Paper and Styrene Structural Design
This three-dimensional model represents the TMT Telescope at 1/250 scale. It combines paper with 2mm-thick styrene and uses mirror paper for the primary-mirror area.
A model assembled from 14 A4 sheets
The finished model measures W240mm × H240mm × D250mm and is assembled from parts supplied on 14 A4 sheets. Tabs and fitted joints secure the parts without adhesive. The assembly sequence is provided on one A2 guide, with explanatory information on the reverse.
Structural design and prototypes
White models were produced before finalizing the product specification to review the three-dimensional form and part connections. The overall model, views from different angles, joints, and mount area were examined while developing the construction.
Cardboard prototypes preceded the styrene model. They were used to consider the basic three-dimensional construction, size, and part layouts before developing the product specification that combines multiple materials.
Specifications
The parts and assembly guide are packed in a dedicated box with shrink wrap.

External Use and Outreach
The National Astronomical Observatory of Japan (NAOJ) distributes a TMT paper craft designed by Kyoko Kanekawa of Honyaplan, with a design credit on the page. This downloadable paper version differs in specification from the styrene-based 1/250 model shown here.
NAOJ’s school outreach report, published in January 2022, shows two TMT models assembled by students at Fukiage Junior High School in Ome, Japan, for an astronomy lesson.
The JpGU 2024 quiz rally listed the TMT 1/250-scale model (3D puzzle) as prizes provided by NAOJ’s ALMA and TMT projects.
The 1/250-scale model is also sold as a commercial kit in Honyaplan’s online shop. Honyaplan continues to produce merchandise sold at NAOJ events.
