This is a simple drag knife holder for Roland-type drag knife head.
Apart from the attached stl files for 3D printing you will need:
1mm x 18mm x 40mm compression spring (example spring)
2pcs 6mm x 70mm linear rods (example rod)
2pcs LM6UU 6mm x 12mm x 19mm linear bearing (example bearing)
Roland-style drag knife head (example drag knife)
3 pairs M4x16 screw and nut
Remarks
You will probably need a small hammer to push the rods into the appropriate holes in the plastic parts.
the small ring is used to hold the top side of the spring. Use super-glue to stick it under the top plastic part.
