This is based on my original WireZipper
This one is widened to 20mm and still 18mm tall without the lid. It's got thicker fingers at 1.6mm vs 1.2mm and a thicker base with holes for M5 hardware. The base is 3.5mm thick so M5x10mm bolts will still work fine in your 2020 series rails.
All bolts are on center!
This comes in 3 lengths 50mm, 100mm and 180mm with a tee and elbow too. Print without support flat sides down. I use PLA but ABS works really well for these too. I have snapped some of the fingers off with PLA.
