Piper 2 - Z-Cable Chain

thingiverse

This is a Z-Axis Cable Chain for the 1/2" U.S. Piper 2 CoreXY Printer. Parts are designed to fit snugly into EMT tube on left rear gantry when viewed from the front of the printer. To assemble the right-hand side, mirror z-chain-frame.stl in your slicer. Print the following quantities: (1) z-chain-frame.stl (2) half-inch_emt_insert_2mm-rev3.stl (1) z-chain-gantry2.stl (1) half-in_emt_mount2.stl (?) cable_chain_link.stl (?) cable_chain_clip.stl Purchase the following parts: (2) 6-32 x 2" screws with nuts (2) 6-32 x 1/2" screws with nuts (2) #6 washers Assembly Instructions: 1. Insert a nut into each half-inch_emt_insert_2mm-rev3.stl. 2. Slide a washer over each screw hole on the z-chain-frame.stl. 3. Thread a 6-32 x 2" screw through the washer and into the z-chain-frame.stl part. 4. Screw on half-inch_emt_insert_2mm-rev3.stl to each 6-32 x 2" screw. 5. Insert assembly into EMT tubes at left rear gantry corner. 6. Assemble as many cable_chain_link.stl as needed to form a chain, approximately 22 for each side on a 400mm high system. 7. Connect the cable chain to the mounted z-chain-frame.stl assembly. 8. Attach the z-chain-gantry2.stl to the other end of the cable chain. 9. Mount the z-chain-gantry2.stl to the Z-EMT pipe with half-in_emt_mount2.stl and two 6-32 x 1/2" screws and nuts at about halfway up the pipe, noting that this will be mounted at a slight angle due to the non-parallel design of the z-chain-frame.stl assembly.
