Tiny Trak Chassis for N20 Motors v2.0

thingiverse

This is the second generation body design of my TinyTrak \r\n(v1.0 here: https://www.thingiverse.com/thing:2930903 )\r\n\r\nTiny Trak is a Lego rubber treads based micro rc tank.\r\nPlease join our facebook group for more information and ideas.\r\nhttps://www.facebook.com/groups/181517579149618/\r\n\r\nI've designed the chassis specifically to work with N20 motors which are easy to find in geared low voltage configurations.\r\n\r\nYou can easily source different gear ratios on eBay. \r\n\r\nI'm using 6v 300rpm motors powered by a 1S (3.7volts) Lipo battery.\r\n\r\nFor the freewheels, I've modified the original Lego axles and secured them in place with CA glue.\r\n\r\nIn this current design, I'm utilizing my own WiMo v1.0 Wifi motor driver board to control the tank over the free RCWController app. Alternatively, you can use a RC receiver and brushed ESC to drive the motors.\r\n\r\nI've used 2mm thick, 3mm diameter Neodium magnets to attach the top part of the design. You can either push the magnets into place or glue them with CA. \r\n\r\nUnfortunately, my hard disk crashed recently and I lost all my Cura profiles. As a result, I've been using Makerware software and the default ABD profile to print 0.3mm layer thickness for a fast test prototype. This is why my end results are somewhat subpar.
