Wooden and paper astrolabes
Though the vast majority of surviving astrolabes are made from durable materials such as brass, these were lavish exceptions rather than the norm. Most astrolabes were made from cheaper and more accessible materials such as wood or pasteboard.
Due to the more ephemeral nature of these models, the historical record doesn't attest to their true volume.
Durability vs. accessibility
Although less durable and perhaps less precise than their brass counterparts, the cost of these cheaper materials made these models far more reasonably priced. Notably, it was not uncommon for universities to loan out astrolabes to students as they would books–models which were most likely made from wood or similar materials.
In 16th century Europe, Georg Hartmann gained particular recognition for his innovative approach to instrument production. In addition to a novel approach to mass-producing brass astrolabes, Hartmann developed more accessible, if ephemeral models. His method involved a blend of printmaking and instrument making, with patrons either purchasing assembled pasteboard or wood instruments, or buying the printed sheets and assembling their own.
Modern accessibility
In the age of the internet, the astrolabe has perhaps become more accessible than ever before. Just as digital media expands the reach of what was formerly relegated to print, so too does it evolve Hartmann's enterprise. Online online astrolabe simulators place the full range of the astrolabe's features in the hands of all who seek them.

In a fitting twist, the most comprehensive astrolabe simulator made by Alexander Boxer features one of Hartmann's own distinctive rete designs.
Go forth, little Lewis
With the astrolabe open to all, all that exists as a barrier to entry is the knowledge required to use it. Luckily, this knowledge is just as available! Whether you reference Chaucer's own treatise, the BC Gnomonics resources, or any of the many other educational tutorials, instructions, and demonstrations archived online, mastery of the astrolabe is just a few clicks away.
