Toroidal propeller launcher (snap-fit model)

● About printing

All parts can be printed without support.

We recommend printing with PETG or ABS filament. 
It also works with PLA, but it may break if you pull the rod hard.
The printed parts in the image were made using PETG and ABS filaments. The infill is 30%, the nozzle is 0.4mm, and the layer height is 0.2mm.

The combination of Propeller_90mm.STL and gaer_rod_20mm.STL is optimal for playing indoors, while the combination of Propeller_150mm.STL and gaer_rod_25mm.STL is optimal for playing outdoors.

● About assembly

(1) Insert long_axle.STL into handle.STL and small_gear.STL.
      Please be careful about the direction of the axle.
