Issue 436 of Miniature Wargames (August 2019) has a five page 'how-to' article on scratch-building this Star Trek Shuttle for 28mm gaming. The full tutorial, written by me shows how I re-drew scale plans, built the shuttle and painted it as well as sourcing some suitable hull decorations. The magazine is available from Warners, your local gaming store or W H Smiths in the UK.
The model was built on a foamboard core with plastic card cladding and bits from the spares box. It was painted with 'rattle-can' spray paints and acrylics and finished with home-made and scrounged decals and labels.
In addition to the Star Trek Shuttle, there are another two 'how-to' articles and a number of early Tolkien First Age scenarios. The magazine also includes the usual reviews and eye candy.
