Parts are designed for 0.2mm layer, 0.4mm line width. **PART LIST** In addition to the 3D printed parts (2 caps, 2 plugs, 1 socket, 1 knob, 1 anchor), you will need: 3 - 1/4"-20 nuts 2 - 1/4-20 x 1" long socket cap screws 1 - 1/4"-20 x 3" long hex head bolt 2 - 1/4" washers 2 - 8-32 x 3/8" long screws 10 - #8 x 1/2" self-drilling sheet metal screws 2 - 608 skate bearings (sealed) 1 - 36" long, 1x1", 1/16" wall aluminum square tube 1 - 35.75" long, sch. 40, 3/4" galvanized steel pipe 1 - threaded replacement mop handle 1 - 36" long piece of foam pipe insulation (for 3/4" dia. copper pipe. **ASSEMBLY** (1) Press 1/4-20 nuts into the hex sockets in the 2 plugs and in the anchor.
