Mica power holder

Shelf to replace the gridfinity ones which takes 7 slots for small bottles. 27mm in diameter and 49mm high. Allowance for a 12mm, 31.7mm diameter lid on the bottle. I did try a shelf compatible with the gridfinity shelf, however, space was tight. By replacing the whole shelf I pinched a bit more space at the bottom to make the bottles fit without hitting other shelves. Standard print setting should be fine.
