Helix lift, scad customizable, gravitrax compatible

thingiverse

I'm watching a YouTube video at https://www.youtube.com/watch?v=wv6l_4RcBLU. It's about a custom Helix Lift Escalator, compatible with Gravitrax. STL files are prepared for a 100 mm tall lift and can be adjusted in Scad to change the height. To build this composition, you'll need a motor with gearbox, an 18650 battery, a battery holder, a switch, two screws (3x12mm), and some glue. You might also need to adjust the upper part for the engine itself. When assembling the battery box terminals, make sure they're soldered correctly to the switch and motor, paying attention to polarity. Here are the parts I used: - A geared Micro N20 Motor DC 3V-6V from eBay. - Low-cost 18650 lithium-ion batteries also found on eBay. - A single 18650 holder that I purchased on eBay as well. - A Black Latching On/Off Mini Torch Push Button Switch (YC) that I bought on eBay.
