1515 double clamp for Kossel XL

thingiverse

Attach extra verticals to strengthen 1515 supports on Kossel XL. This double attachment is designed to slide into 1515 extrusion, allowing a second vertical 1515 extrusion to be firmly clamped to it. This effectively gives you 15x40 verticals, with very good radial stiffness. A key point is that you can attach to a 1515 beam without having access to the end of the slot to put a bolt in - so you can add the extra verticals without disassembling your printer. I have used three attachments per vertical on my Kossel XL. You need two 20mm M3 screws per attachment.
