1.5" 8020 snap-in PVC pipe clip
This is a snap-in pipe clip that fits in the center slot of 1.5" 8020. Like my other 8020 snacks, this one hold the 8020 tight and won't slide without a LOT of force. A piece of 1" PVC pipe snaps right in and is held firmly in place.
I use it in my printer to hold two filament feed reels. There is another piece of pipe a little further forward that keeps the filament away from the Z-axis drive belt and provides almost perfect vertical feed to the extruder.
