This is a washer replacement part for Fansproject WB001 Warbot Defender's helicopter blades. I created this because I accidentally broke mine, so I hope that this may be useful for anybody who is in a similar situation as I was.
This kit includes two (2) of the same washer since a single washer is too small for shapeways to print, and plus you have a backup one in case you break the first one. This item is being sold with zero markup due to simplicity of the 3D model.
