Horseshoe – shoulders for astromech
Robotix Toys
Getting stock metal cut for the shoulder “horse shoes”
The shop used two types of saws – one with the material going vertically
The second was with the material perfectly flat. Massive difference
Beskar2D2 – The dome has arrived
Beskar2d2 shoulder motors
