Points Motor for G Scale with Spring
thingiverse
I was concerned that my previous rack and pinion points drive designs needed preciscion servo setting to avoid straining parts. Also, accidental train traffic "against" the points can derail trains or damage the drives. So this design includes springs that allow the points move in a similar way to the original LGB mechanical manual drives. https://youtube.com/shorts/MsCF-XoNr_I Compression Spring, are: 304 Stainless Steel,4mm OD,0.4mm Wire Size, 20mm Free Length, (available Amazon when I looked) Screws are #4 4mm countersunk for the lid. Use a 2mm screw if you have one, for the drive link to the actual poits. The full set of parts includes gears with varied "hex" holes to match your servo and printer. I print at 0.2mm layer height and with horizontal expansion of -0.1mm.
