thingiverse

An indicator bell signals when your print is complete. You will need: One M5-.80x50 Pan Phillips Machine Screw Two M5-.80 Hex Nuts One M5-.80 Nylon Insert Lock Nut A 4.76x44.4 tension spring from a kit, such as the one found at https://www.aliexpress.com/item/32947865117.html?spm=a2g0s.9042311.0.0.340e4c4d2HLVac, is also required. This set of springs is highly recommended to have on hand. The bell from this Amazon product: https://www.amazon.com/gp/product/B072FJF4KD/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1, is needed. Remove the bell part and discard the rest. The bell comes in a 3-pack, allowing for multiple creative possibilities. Remove the loops from the ends of the spring using wire cutters. Insert the spring into the hole on the bopper holder, ensuring it fits snugly. Attach the bopper to the other end and fit the bopper assembly onto your printer's carriage by snapping it onto the two bearing spacers. Press a nut into the bell mount's nut-shaped hole. It should be a tight fit; use pliers if necessary. Insert the screw through the convex side of the bell, followed by a nut on the opposite side and screw everything firmly together. Screw the bell into the nut until it protrudes from the other side. Securely attach the nylon locking nut to the reverse side of the bell mount. Snap the bell assembly onto the far right of your x-axis, fitting it onto the bearing spacer at the rear. You may need to adjust the front-side nut to align with the slot on the bell assembly. Modify the Gcode in your end script by changing this line: G1 Y{machine_depth} ;Present print To this: G1 X{machine_width} Y{machine_depth} ;Present print and ding the bell Congratulations, you are now done.
