Reention DP-9 - Layout design to maybe fit 98 cells (14S7P)

**Important!** Rename DP-9 Structure X.f3d**.stl** to DP-9 Structure X**.f3d** The [Reention DP-9](http://www.reention.com/en/xzdch/yingwuxilie/114.html) can house exactly 91 cells with stock cell holders. It's possible to build an 13S7P (91 cells) or 14S6P (84 cells). Since I wanted to go for 14S/52V, this was a waste of space and I tried to figure out a layout design for 14S7P (98 cells). This was an approach and I wasn't able to investigate further or make it fit. In my build I used VTC6 which have a diameter of 18.3mm. This made the whole layout design to wide. **BMS:** Initially I planned to use an [Speedict Neptune 15](https://www.speedict.com/tech-specs), since they claimed to be only 9.5mm thick. In reality they are thicker. As alternative, it's possible to buy cheap [bluetooth smart BMS](https://de.aliexpress.com/item/32794186005.html) and upgrade Mosfets + Shunts: [Endless Sphere - BMS modding for more current](https://endless-sphere.com/forums/viewtopic.php?t=95853)  Instead of thinker on this, I decided to go with this layout for an 14S6P pack:  Feel free to play around with the files!
