Description
Pre-order. The first kits ship after our printed prototype has been assembled and checked. Estimated dispatch: 4 to 6 weeks after your order. Every dimension is provisional until then; if the prototype changes the design, you receive the revised kit. You can cancel for a full refund at any time before dispatch.
Adds 3U to a rack. Its posts butt onto the ones below and the straps bolt across the joint, so the rack grows by exactly 3U with nothing between the sections and no step in the mounting pattern.
Printed parts (PETG): 4 x post, 4 x splice strap, front, 4 x splice strap, side.
Hardware included: 36 M6 heat-set inserts (pressed before shipping), 40 M6 nyloc nuts and 40 M6 x 16 socket screws — 16 across the front of the joint and 24 through the sides.
