fischertechnik N20 Mini Power Motor system by juh
by Thingiverse
Last crawled date: 3 years, 1 month ago
Changelog:
2018-09-25: (1) Corrected an error in Enclosure_grooved_v4.stl, the groove was 5mm short, now it is correctly 25mm. (2) I added a version of the enclosure parts and drilling aid for 4mm square brass rods, which are harder to get (where I live) but are much easier to cut and drill. Look for the files named ...v5_squareRods, images at the end of the gallery.
2018-06-13: pinion & gear adapter now has filleted corners
This is an enclosure for the cheap N20 gear motors, which are available e.g. from ebay with a number of different RPMs. The enclosure makes the motor compatible with the fischertechnik construction toy system, turning it into a 30x15x15mm size building block. The motors run with 12V, but 9V as used by other fischertechnik motors work fine, too.
Two versions of the enclosure are provided, an ungrooved one and a grooved one. The latter offers more connection alternatives but leaves the gears open to dust and other foreign objects.
Several fischertechnik-compatible adapters for the N20 D-shaped 3mm shaft are included:
Clip-on axle adapter (similar to Rastachsenkupplung 15) with and without locking screw
10 tooth gear (similar to Zahnrad Z10) with locking screw
Adapter for bigger gears (similar to Flachnabenzange)
Pinion and gear adapter (similar to ft Hubgetriebe) for fischertechnik 0.5 module linear gears with printed-in-place gear and matching worm gear m0.5. Needs a grooved enclosure. Warning: the worm gear will wear out under stress (at least if printed with PLA), so this is mainly meant for demonstration purposes. Please report if you get better results with other materials.
Additional non-printed parts and tools you'll need:
4mm solid brass rod for the connectors
high quality 2.4mm metal drill
drill rig
soldering iron
super glue
fixing screws 2x2mm, as needed
