Amoeba or HoneyBadger Battery Extender

thingiverse

We've struggled to find the perfect size LiPo battery for our son's Amoeba, so we decided to design our own stock. The store that sold it didn't carry the correct battery, forcing us to use the online store every time. We had often discussed creating our own custom stock, but PLA isn't ideal for a full stock due to its limited strength compared to factory polymer Ares. So we designed this extension, allowing our son to use full-length LiPos or NiMh 9.6v batteries - using NiMh is sometimes a good idea for kids since the internal MOSFET always draws current and can kill a LiPo within days if left connected. The unit press-fits into place, with you plugging the stock battery box end into this piece and threading the rear pad through. It should click securely in place when pressed firmly. We've used this extension at two AMS events without any issues. To add extra strength, we recommend printing it with 75-100% infill. If you feel like redesigning it to make tab-lock functional, that's your choice - but we didn't find that necessary since it press-fits securely into place. Print Settings: * Printer: CTC * Rafts: Doesn't Matter * Supports: Yes * Resolution: .4 * Infill: 80 Notes: ABS or PLA should work fine. We preferred PLA because it's stiffer than other materials. Post-Printing: * Installed. How I Designed This: I designed the extension the old-fashioned way - using a caliper and ruler to figure out the dimensions, then starting with blocks in 123dDesign and carving them to match the shape. I printed about six test pieces before getting it right.
