3mmx1mm. They fit into the sockets in the wrists more or less perfectly (held in place with a small amount of
GS and superglue.).
Stubs on the hands were shortened by a couple of
mm and a magnet (polarity matched to the socket) was glued into place there.
Weapon muzzles required making a socket to fit and patching with
GS.
Personal teleporter on top was made from a couple of
CoD lighting bits.
Here is is armed with heavy incinerator, heavy psilencer, greatsword and personal teleporter.
This one shows the magnetised points. That's the psilencer muzzle up on top and the sword hand on the right arm weapon mount.
