**Eachine Razor FPV plane new battery hatch cover** ------------------------------------------------------------------------ *This cover allows for the use of a triangular prismatic 3S 18650 battery pack, as well as the mounting of Split Cam boards, both 20mm and 30mm sizes* **WARNING**: running 3S on Eachine Razor with the stock Propeller and Spinner is VERY RISKY. These are almost impossible to balance and Razor's nose cone and motor mount are fragile. The combination of a 3S battery and the stock propeller-spinner causes the nose to break apart. Just check: https://www.youtube.com/watch?v=msWhqa7nkV8 *In summary*: 3S must be used with good quality, well-balanced props, and a good quality spinner link to OnShape CAD design of this part [here](https://cad.onshape.com/documents/16e7257e6759bdccb79b6244/w/c670e5a3ead27b401c18e1dd/e/a3b1aff3bc42b987d92fff46) Requires: - 6mm diameter x 3mm heigh neodymium magnet - M3 screws or - M2 screws Create the threads on the holes on the pilons using metal screws before attempting to use plastic screws This serves as base for: - Raised camera mounts for the Runcam Split of Foxeer Mix, [here](https://www.thingiverse.com/thing:4786082) - Raised camera mounts for the VC400, [here](https://www.thingiverse.com/thing:4786946) **Printing** ---------- Avoid heavy finished parts by using thin walls (1 - 2 layers) and by using low Cubic infill (10-15%) Improve finishing by printing in the upright position. It will require a lot of supports, but the part upper layer improves a lot. Use ZigZag 10% density support. Also the 0.1mm layer heigh is recommended.
