Gridfinity baseplate "anycubic" topper that fits 2020 extrusion for printers like TenLog TL-D3 Pro. I added a channel for an extruder "VGA" cable. This frees up the top of the 2020 rail for gridfinity baseplates. I place one normal topper baseplate in between the two with the channels.

I'll upload a better photo once my M5 screws and T-Nuts arrive.
