45 degree angled wall or rail mounted flag pole holder for small decorative flags with ~6.5 mm poles. Reinforced. Printed with 3-4 walls, it's strong enough for most purposes, PLA should be fine for indoor use, go with a more temperature resilient filament if needed for outdoor use.
Note my photo of the flag mounted shows the holder mounted by a single pushpin. Use that for scale.
