Description
As a compliment to my Pebble Wiper (https://www.printables.com/model/565553-e3d-tool-changer-pebble-wiper-v21) I created these wiper bars to wipe off excess oozed filament which may have been extruded by the hotend while the tool was in standby.
The design uses M5 screws and T nuts to affix the bars to the central aluminum extrusion. I cut small rectangular strips from a thin silicone mat. The silicone is sandwiched between the bar and the holder and countersunk M3 screws keep the whole thing together.
