MKIII - Disc

This part can be used with the MKIII wind turbine (https://www.thingiverse.com/thing:2851306).

The original disc design showed the designer's impressive technical and mechanical engineering skills.

There were a few downsides to it that inspired me to design this simplified version.

• The original version required a lot of additional parts which made it slightly more expensive and increased the overall complexity.
• The blades wouldn't lock in place at a certain position even with the blade settings tool. They started to get loose after a while.
• The blades needed a hex nut added during printing (had to pause the print) which is more something for advanced users

When using this disc, the following parts of the original parts listaren't needed anymore:

• PP_3001_01 Disc
• PP_3002_01 Crank
• PP_3003_01 Pitch Arm
• PP_3004_01 Piston
• PP_3005_01 Piston Cover
• PP_3011_01 Plain Pitch Bearing
• CP_5003_01 M5 x 40 Bolt
• CP_3003_01 M3 x 12 Bolt
• SP_1003_01 Pitch Spring
• PP_3010_01 Blade Setting Ring

As the blades are hold in position via CP_4005_01 (M4 x 50 bolts), the screw won't stick out as long as before. Not sure if this is a problem. You can always upgrade them to a longer version such as M4x60 or M4x70.

Design was made with Fusion 360. You should be to access the design via the link below in case you want to make your own modifications. https://a360.co/3gbfkWB

This print needs support for the 3 blade sockets. If you can, please use PVA to print the support structure. Otherwise PLA should be fine too. Might require a little bit of sanding. The blades should require a little force to push them into the sockets.
