Dao Trọng Lực (Cập nhật)

Gravity knife fidget toy to keep your hands occupied.

Updated with a safe blade and two comb blades.

Assembly:

The Peg should be printed two times.
All the tiny blobs or other printing defects should be removed if any.
BaseBottom and BaseTop should be press-fitted. Use glue if needed. (I used a hammer to fit them together, so no glue was used)
Check if Blade moves smoothly in the Base. Use sandpaper on the blade if needed.
Press fit Peg into the Blade when it is moving smoothly in the Base. Make sure to center the Peg.
Put the Base into the Case and insert another Peg.
Use sandpaper if your tolerances are not perfect.

Layer height: 0.2mm
