Model information
Description
A sheet pulley for RC sailboats. The author states it fits Footy, Micro Magic, and RG65/DF65 class RC sailboats. The pulley diameter is approximately 8mm. The pulley block is designed to accommodate an M2 threaded screw to fix to the servo arm while allowing free rotation, provided it is not overtightened. The author notes it works fine without ball bearings.
Two versions are provided:
- A single shot version (the author notes this requires support which may be difficult to remove).
- A two-part version (the author notes this requires superglue but may print nicer).
For the pulley axle, the author used a copper metal rod from a bead store, noting that stainless steel or hard aluminium rod may be better. The author reports printing from eSun PLA+ for strength and abrasion resistance.
