Cetus 3D Extruder Drop Stopper

thingiverse

The major drawback of Cetus 3D printers is that when power is shut off, the extruder drops, causing the print head to crash directly onto the bed. To secure the printed part, place it on the Z axis stepping motor. Pass a rubber band through the hole. It's crucial to use a thick rubber band strong enough to support the extruder, X-frame, and stepping motor. In case of fall prevention, stop the rubber band at the upper screw. This mechanism prevents accidents by relying on the strength of rubber. The Z axis stepping motor can hold considerable weight without any issues, making it unnecessary to worry about rubber band load. Unfortunately, this design cannot withstand high temperatures from the stepping motor, so ABS filament is recommended. It's advisable to use other printers for output.

Metal hooks can be installed as an alternative.

Caution: The upper M3 screw is too short, so exchange it with a longer screw. A 12-14 mm long M3 screw is recommended for added strength, mimicking the original product design.
