Escornabot pieces for ball and 4x1 battery holder

Pieces for the Brivoi compactus, an Escornabot robot. Original project (at https://escornabot.com) is designed for a 2x2 battery holder, so I design pieces for a 4x1 battery holder.

If this is your holder, use this pieces instead of the originals BallCaster and BatteryBracket pieces.

Depending on the printing adjustment it may be necessary to file the lower hole.

The pieces have some irregularities almost negligible (depending the resolution) when printed because I'm newbie modeling and using 3d design programs.

Now we can rename it to Brivoi not so compactus ;)
