Begode Blitz - Bumper Replacement

This is a bumper/display holder/handle replacement for the Begode Blitz.

=== 2025-01-10: Version 2 of this bumper replacement. ===

I had a bunch of design goals with the version 2 of this bumper replacement:

1) Move the handle to a more forward position
1 a) ...more comfortable for seated riding
1 b) ...more comfortable when lifting the wheel
1 c) ...less likely to hit your legs when standing
2) Move the display to a more protected position which will still be visible from above
3) Add some more bumper surface in the front to protect the LED plastics below in case of impact

The V2 front part is compatible with the V1 rear part so if you already printed the V1 version you can re-use those and only need to reprint the front parts.

Other parts included for version 2 of the bumper:

- Grab_Handle_V2 or Grab_Handle_Grub_V2 - The grub variant allows for easy insertions of M4 hot melt inserts, the non-grub variant instead has 3D printed threads for M4 screws (20-25mm length recommended),
