Abstract

An apparatus to receive a filament material and to move the filament while guiding a direction of movement of the filament comprising:

• • a metal block that defines a first guide passage sized to receive the filament;
  • wherein the block includes a first plate that includes a first surface that defines a first groove and includes a second plate that includes a second surface that defines a second groove; and
  • wherein the first and second faces of the first and second plates are in abutting contact with the first and second grooves aligned to define the first guide passage;
  • a drive mechanism configured to move the filament into the first guide passage.
