From the update:
We have just added a new category to our shop: Scratchbuilding! For starters, there are two sets of girders, as well as two sets of newly released handwheels. In the future, this category will contain more items that are no standalone models, but are valuable additions to scratchbuilding projects. Primarily aimed at 28 mm scale, these items might be used for other scales as well, depending on the intended use.
