Case In 3D Cho Heltec V4 (GPS) Đã Sửa Lỗi

There are several problems with the original case, this remix aims at solving them all:
- Can't enter dfu
- Can't connect and disconnect battery
- There is to little space for the battery (thickness)
- The battery pushes onto the gps cables it can lead to unplugging the gps
- The case uses M2.5 screws that can strip the plastic easily especially with the battery pushing the halves apart.
- There is no space around the antenna screw making securing it difficult
- Lots of sharp edges that are hard to print 

Parts needed:
3x M3x12mm screw and CNC Kitchen M3x5.7mm brass inserts.
