Your extruder broke but you don't have time to wait for a spring to arrive in the mail. Relax. This extruder has a 3d printed spring.
Print it, then assemble it and install it. Be careful not to use the experimental printed screws because they're probably flimsy for actual use (the extruder has been tested and works but the printed screws are untested).
