Nudger For Telescope

A GIZMO FOR NUDGING (Small Movement) OF DOB TELESCOPE (3/19/2026, Added GIF Video of Knob Tweaking and the Decorative-Ring (STEP File) for it) This uses 3-Planetary Gears, SunGear and RingGear to reduce the Rotational distance of the Driven-Wheel. One full Turn (by Hand) of the Knob will cause the Driven-Wheel to turn 1/4 of a Turn, thus enabling finer movement as is often desired. The Driven-Wheel will cause movement of a Dobsonian-Rotating-Base/etc by Stiction of the Driving-Wheel against the Base. The Interface between them is accomplished by a Rubberband (or, Silicone band cut from a Silicone Mat) . See below. Using a Spring will keep them in Contact and User can Disengage is desired. User can prefer to Not use the Spring, thus freeing the Base to turn freely - thus, User will need to Press the Knob toward the Base to Move it... Your preference. The Base: Three Options: Left or Right (the Finger/Spring side) and Make Your Own (shown in GIF video). Uses ORCA Slicer (similar to Prussa/etc) Assembly: File/Sand as needed - Smooth movement is easily attained using commonsense Filing and Sanding. Lubricate moving parts with very small amount of Petroleum-Jelly. For some Users, depending on their hardware, the Screw/Washers/Nuts are Optional. If needing/preferring to often remove the Knob and Insert, Don't use the Screws/Washer/Nuts. Some may need to only remove the Knob and not need removing the Insert. Printing: Both STEP and STL files are provided Print Parts, especially Gears at 100% Infill. Adjust Print-Height is needed Some Parts can be modified as Whole and/or manipulated into individual Parts in Slicers. Especially handy if wanting, for example, to only lengthen the Height of the RingGear, Wheel...etc. Consider Seam-Alignment (Random or Aligned... will affect amount of Fileing/Sanding and Smoothness Material - doesn't matter File/Break Elephant-Foot-Edge (the enlarged portion that gets squished into the Print-Bed. Parts: The Pins for the Planet gears are 3mmX10mm. The holes for them will provide a slight Friction-Fit and need to be Pressed into the holes. The Screw/Nuts are M2 (or similar size) I prefer these inexpensive Rubberbands but, Silicone strips cut from the Mat is also very good (better Stiction), if wanting to fuss with it. I've done many but prefer the Rubberbands...
