I'd like to 3D print a clip that connects two metal tubes of a wheel chair.
My requirements to the material are:
1. it must be usable outdoors (UV light, rain)
2. it should be stable up to 20 kg weight
3. one clip should cost less than 30 Euros (about 45 cm3)
Metal sintering seems too expensive. Could #PETG work? Maybe someone can point me in the right direction which material is suitable.
