Crayford telescope focuser v1.0.1

thingiverse

v1.0.1 (2021-10-26) Simple, cheap,yet effective crayford focuser. Created in consideration that it will be 3d printed, so all models are optimised for this process. Parts used: • shrink tube (7 mm in shrinked state) • 623ZZ bearings x4 • M3x10 x6 • M3x20 x2 • M3x25 x1 • M3x40 X1 • M3 nut x2 (use M3 screws with cylindrical hex head) Shrink tube is used to put un roller, so it would not slip on cylinder. Feel free to ask if you need anything, like tube mounts for other tube diameter rather than 200 mm. planned uptades: • create mounts for 150 mm and 100 mm tubes in 3 different heights • add 2 more heights for 200 mm tube mount • file project v1.0.1 (2021-10-26) • fixed main body to tube mount hole location • adjusted collet nut size
