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 setting to use a traditional recipe and mined result (default: disabled).
Startup setting to enable the No Long-handed Inserter Challenge (default: disabled).

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.
