openGrid - 6mm hex Multiconnect lock snap

Remix based on work from @Wayward_Electron & @david.dHex slot increased to 6mmEasier to turn / less chance of stripping if the first layer sticks together a littleHex slot goes through the full depthExtra leverage makes it significantly easier to removeTriangle marker added to make it easier to visually identify when the snap is lockedPoints at an angle when unlockedPoints up / towards the grid border when locked Printed with 4 walls & 50% infill – could probably do with less, but the time / filament difference wasn't much.
