Manual (Non-electronic) PonyTrope

thingiverse

Human: I adored Keleyegan's original PonyTrope but wanted a simpler, non-electronic version. I didn't want to buy a motor, Arduino, LEDs etc., and more importantly, I was intimidated by the thought of learning to program an Arduino. What to do? I decided to create a manual remix. This remix uses a non-motorized hub to spin the ponies. A pulley is attached to the bottom but I haven't yet designed the drive pulley for a hand crank (I just spin it with my finger for now). I repurposed two old skateboard bearings that my son had lying around for the shaft supports. The shaft is an 8mm x 80mm hex bolt. (There is a parts list in the PDF file.) This remix uses the hub_short.stl from the original thing and only requires three additional parts and some hardware available at any hardware store or big box retailer. I use a strobe app on my phone for the strobe light: https://play.google.com/store/apps/details?id=com.easylabs.strobe&hl=en It works well, seems to be a true strobe and has an adjustable frequency. The manual PonyTrope works pretty well considering it is non-motorized. Make sure the room is totally dark for best effect. Printer Settings: Printer Brand: LulzBot Printer: Mini Rafts: Doesn't Matter Supports: Yes Notes: Print the Hub Carrier and Hub Pulley with recesses for nut and bolt head down. Use supports for the recesses. Post-Printing: I tapped the holes for the 6-32 bolts in the Hub Carrier. You can try to let the bolts cut their own threads but tapping them makes assembly easier.
