A matching pair of faceted desk organizers that both print without supports: a pen holder (75 x 79 x 100 mm) and a phone stand (72 x 88 x 97 mm) with a 65 deg backrest and a charging-cable channel. The 3MF places both on one 180 x 180 mm plate, so the set prints in one go (about 164 g PLA). Cheaper than buying the two singles.
