Bulkman3D Queen Bee Pro Drag Chain Parts

The new QueenBee Pro CNC router kit from Bulkman3D includes their drag chain kit with the purchase. However, this kit doesn't seem to come with the hardware required to mount to the QueenBee Pro, which has different extrusion end brackets than the WorkBee, not to mention the linear rails that interfere.

This collection is modified/remixed from Josh's (@IDIM - “I'll Just Do It Myself") components posted on a CNC-oriented site. His parts fit the original Ooznest, but not the Bulkman3D version of the QueenBee.

There is no X-Axis stationary mount, because that's the one pieces that's held with a t-nut that's already included.

I've also included a replacement for the 2040 end covers, so that you can nicely route the Y2 motor cables through the rear 2040 extrusion for neatness.

In addition to the STL's, I've provided the reverse-engineered STEP file with all of the parts, should you wish to modify them to suit your own needs.

How I Designed This

In Fusion 360, for simple STL's such as originally imported, you can turn off design history, then convert the mesh to a solid body, convert that to a boundary fill, then use it to sketch out the major geometry, extruding replacement bodies and features to match the original.
