OE OTF RE : Top Button : Slim

Please refer to the crowdfunding project for model details.

Lubricate thoroughly with cooking oil. Use PETG HF material for good durability. This is a precision model, essentially a benchmark test of your equipment. Before giving a "no" or negative rating, make sure you understand what you are doing.

Carefully inspect all parts. Ensure there is no elephant foot and warping. (To avoid warping, please use glue. Alternatively, try increasing the temperature of the first print bed and filament by 10°C.)
Inspect the overhang (green section in the image below). It must let the blade runs smoothly.
Lubricate at least all blue sections. Lubricating all internal parts is strongly recommended.
