Our group has had all our items taken away, including component pouches and arcane focuses. Certain materials definitely seem like something prestidigitation can make as a trinket such as a magnifying glass.
You create a non-magical trinket or an illusory image that can fit in your hand and that lasts until the end of your next turn. (SRD V5.1, p. 170)
Assuming the material is cheap (no cost stated) and is not consumed by the spell, can prestidigitation make the material components as trinkets? Even if the person casting it can't use it (since they've used their turn) can another character hold and use it?
