Иногда нужно в пластик вклеить шпильки или всякие резьбовые втулки. Какой вообще стоит делать зазор, чтобы особо не болталось, и точно влезало?
Печать ABS. Насколько сторонние сервисы печати учитывают усадку - не знаю.
Допустим, простые отверстия, где нужна точность, проще пройтись разверткой. Но париться с таким под вклейку явно излишне, и форма там не всегда круглая.
