Thanks to the release, and terms of use, its now possible to have a free to use for various uses micro blocks.
See Immibis Core with microblocks
Planned features:
1. Microblock versions of Re-enforced glass/stone, bronze block, tin block, uranium block, and anything else that would make a nice decrative block.
2. Microblock coverable version of various IC2 cables, except for the 3x insulated HV cable (its almost a solid block anyway)
3. Overrides existing cables and uses the same ID
Current mod status:
1. Decompiled Immibis Core to investigate data structures of covers.
2. Write up list of extends/inplements header changes for cable blocks.
3. Pondering how best to deal with Construction Foam, in and around cables. Should it co exist with microblock covers, behave as if a cover itself, or be disabled when a cover is in place.
4. Wrote method to take ItemStack (eg mod blocks) directly, its untested until I manage to compile the code.
