Orbital Mines for Battlefleet Gothic (two types)

Orbital mines for tabletop space games e.g. Battlefleet Gothic. There is a 1 mm hole in each for a post to support them, 11mm diameter from tip to tip. I suggest 20mm laser cut mdf bases and 1 mm brass rod to finish them. Two different kinds, one spiked and one more traiditional looking. Both types have x4 engines for translation towards the target.
