Any PLA ABS or PetG
I used only supports from bed only on spindle with rafts, I printed it on its side for strength. The main holder only needs slight support and the nuts don't need any support.
Just clean up from supports of spindle and main holder. Push bearings in spindle then slide 8mm rod through. Place nuts on both ends of spindle and metal nuts on 8mm rod. Slide main holder on to the top of printer (temporarily removing screws to do so).Slide through large roll and put on holder
