K'NEX motor add-on for Snelon's strandbeest

prusaprinters

This is my motorized mod for Snelon's printable strandbeest using K'NEX! BOM3D printed parts:2 spur gears (the large ones)2 drive gears (the small ones)2 inside motor mount 2 outside mountK'NEX parts1 green battery motorgrey rod (approx. 7in. long)2 rotation locks (IDK what they're actually called, but they are a small connector-type piece that locks the rotation of connectors/gears/wheels/etc. to rods.)10 large grey spacers5 small blue spacersHow to assembleI have provided a few pictures of the final build but since I decided to print in all black and you can't see much here's written out instructions:Not sure if it's just me but when I loaded Snelon's parts into cura slicer, the parts were tiny, so I scaled everything up to 1000%. For reference my short beams are 1.9in (or 48.3mm) long and .075in (or 1.9mm) thick. Also remember that my models have to be scaled to 2540%. My strandbeest has 10 legs and has short axles sticking out of the end frames.Ok now on to the instructions:Step 1) attach the two inside motor mounts to just outside of the middle two frames. The hooksshould bend and snap around the sides of the frames.Step 2) attach the outside mounts to just inside of the end frames. I did not putspacers here, so the curve of the hooks is smaller, but if you did put spacersthere, just use the inside motor mounts instead.Step 3) put the K'NEX motor between the two center mountsStep 4) put the spur gears on the camshaft. They may need a tiny bit of filing in the centerto fit.Step 5) add the drive gears, rotation lockers, and spacers. You can see the order I usedfor everything in one of the pictures above.Good Luck and let me know if you have any questions!Print SettingsPrinter Brand:CrealityPrinter: Ender 3 ProRafts:NoSupports: NoResolution:.28mm or betterInfill: 10% or betterFilament: does not matter pla does not matter Notes: Remember that all of my models need to be scaled by 2540%   Category: Mechanical Toys
