Sky RC - GSM-015 GNSS GPS Speed Meter Battery Cover

Use this to replace a lost Sky RC - GSM-015 GNSS GPS Speed Meter Battery Cover.
I think it's a better fit than the OEM (of which is obviously lost..).

Use supports for the tabs but do not put the supports up to the edge of the lid, see photos for how I did my supports in Simplify3D.

Use a quality filament to obtain nice edges.
