##Instructions have been updated to be more clear and concise. ##Part selection has been simplified to reduce confusion. Follow my project here: https://crunchysann.com/BL/projects/ These mounts are designed to be installed on the HE3D K280 delta printer, enhancing its frame rigidity. This design should also fit other delta printers with 20/20 towers and approximately 340mm tower-to-tower horizontal spacing. ###Instructions for Those in the USA Who Can Only Buy 1/2in-13 Threaded Rods: 1) Purchase: QTY 6: 36-inch long 1/2in-13 threaded rods from here on Amazon, available in packs of three or one per pack at your local hardware store. 2) Print: QTY 6 of "frame support v6_half inch_out.STL" QTY 6 of "frame support v6_half inch_in.STL" QTY 3 of "Crossmember coupling.STL" No support or raft needed, with a recommended layer height of 0.3mm. 3) Mount as shown in images. ###Instructions for Those Outside the USA Who Can Only Buy M12-1.75 Threaded Rods: 1) Purchase: QTY 6: 915mm long M12-1.75 threaded rods from your local hardware store. 2) Print: QTY 6 of "frame support v6_M12-1.75_out.STL" QTY 6 of "frame support v6_M12-1.75_in.STL" QTY 3 of "Crossmember coupling_M12-1.75.STL" No support or raft needed, with a recommended layer height of 0.3mm. 3) Mount as shown in images. NOTES: - Obtain longer rods if you have a larger delta printer that requires supports. - The images provided do not show the mount installed on the front of the printer; you will need to install a separate mount there. Installing two mounts will make the frame rigid in two directions, while installing three mounts will make it extremely rigid.
