Description Bride of Pinbot 4-Face Cube Kit Produced on laser-cut acrylic. Turnkey replacements to mount to your existing rotating face-cube assembly. You get all four faces as shown here, pre-assembled with brand new crystal-clear (permanent) ball guide rails. This reproduction design features guide rails that no longer bolt-on. We use permanently bonded laser-cut acrylic guide rails, to solve the historic yellowing problem with the original (unobtanium) injection-molded guides.
