Chassis for Drawing Bot with Batt Holders

thingiverse

Another variant on MakersBox Arduino Drawing Bot. Both the Pro Trinket from Adafruit and my DIY arduino solution work fine with 6V so I thought it would be a perfect opportunity to try to incorporate my battery packs (http://www.thingiverse.com/thing:1096639) I used the original battery pack design versus the newer slimmer model because the larger space puts less stress on the printed plastic and I had the space under the bot to use them. I soldered the leads to make the 6V pack but only because I was testing soldering to stainless steel. Pressure fit 22 gauge jumpers will work just fine for a solderless build. The result is a smaller bot than my previous model (http://www.thingiverse.com/thing:1287264) with the same functionality. However, thinking past the drawing aspect, a smaller robot may make it through a maze a bit easier... Both work great, and the credit should be given to MakersBox for a great design. Post-Printing Recommend using countersunk M3 screws to mount the ball caster in order to give you a flat area onto which you can position your breadboard with dual-sided tape.
