[Babo] insert: Calipers, Batteries & Allen Keys Combo

Babo insert remix to merge @platini76's caliper+batteries holder and @Willi3D's allen key holder. My generic Amazon digital calipers were too long for the other inserts so I edited the original to fit. The calipers are close fit even with both end walls removed. Battery location changed to the battery size of my calipers. Allen key insert edited and merged into the side. *Updates:24-02-07: Overall profile reduced for better clearance, print profile removed (wrong infill % used).24-02-13: Print Profile Updated; 1 wall, 10% grid infill
