Modular Tank Tracks

thingiverse

Modular tank track system that allows you to attach tracks to most anything. Updates: I added some pictures to cover assembly. I also added a simple mount for attaching it to whatever you need to move. Instructions I'll try and get a more detailed write up done soon. You'll need to use support on the frame pieces for the mounts. I printed the shaft pieces standing straight up and down. The rivet nut sleeve is to reinforce the mounts so the rivet nut expansion doesn't split the plastic. Video of the track running:http://youtu.be/Sgy3i3ZVxlU Overall it doesn't require a lot of support. I used the following parts to assemble this: 5 - (per side) 10mm X 15mm Sealed Ball Bearings (for Traxxas RC vehicles) http://www.amazon.com/gp/product/B00GVMSBMU/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 1 - (per side) for the motor shaft m3 - .05 Metric Coarse Thread 3mm lengthhttp://www.amazon.com/gp/product/B005A1JYK6/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1 6 - (per side) M3-0.5 Coarse Thread 25mm lenght screw. (20mm would probably work better, I think I cut these to lengthhttp://www.amazon.com/gp/product/B000NHTPXI/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 3 - (per side) #4-40 Thread, 3/16" length screwhttp://www.amazon.com/gp/product/B00GX0M17G/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 2 - (per side) m3-0.5 Metric Coarse Threads 10mm lengthhttp://www.amazon.com/gp/product/B00598DI9I/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 4 - (per side) m3 rivet nutshttp://www.amazon.com/gp/product/B00JKG619E/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 2 - (per side) M3-0.5 thread Steel Hex nuthttp://www.amazon.com/gp/product/B000NBIH92/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 30(or so) - (per side) 1/2 inch 18-gauge brad nails (for the tracks) 1 - (per side) Polulu Micro Metal Gearmotorshttps://www.pololu.com/category/60/micro-metal-gearmotors (note: I used the high-power model for the prototypes, They seem to work now, but I did have issues with them stripping out the axels, You may want to go with the medium power version).
