Nearly Completely Printable Spherebot: Update on the Semi-Completely Printable Spherebot! This updated version is aptly named "Nearly Completely Printable Spherebot" and has been designed using Google Sketchup. On February 28, an additional pen mount with a longer stepper arm and longer pen arm was uploaded, featuring two pen rings that are slightly smaller in diameter for better fit. The bill of materials includes 2 stepper motors, 1 small servo, 1 breadboard, 1 Arduino, 2 Pololu stepper motors, 1 power supply, 1 3D printer, 1 bearing (preferably from an old skateboard), lots of ABS (or material of your choice), 6 M3 bolts, 2 M3 nuts, 2 Nerf gun darts, super glue for the dart tips, sharpie ultra-fine tip markers, a small rubber band, jumper wires for breadboard connections, and cheap plastic eggs for practice. Instructions for assembly and printing are provided along with all STL files that have been processed through Netfabb software for improved print quality. Additionally, you may download Mike_linus' Nut Job nut and bolt SCAD file from Thingiverse for further customization. All gcode and Sketchup files are included for easy printing and modification. Please share your input on improving the sphere holder cups for better egg centering during use.
