With Entangled Belts, you can braid with same-speed underground belts.
Simply alternate between pairs of underground belts and entangled belts.

Entangled belts are crafted from underground belts and revert when mined.

Startup option to enable the No Long-handed Inserter Challenge,
the most coveted of all achievements... well, maybe not the most.

Compatible with most mods that modify or add underground belts.

Note: If Bob's Logistics and the inserter overhaul is active, the challenge option will be ignored.
