https://www.thingiverse.com/thing:4762963 iser Extension P-Cap for BORA's Centipede collapsible work stand system. Design and layout matches factory dimensions, and improves upon it. This "P-Cap" design threads on directly, without the need for an additional nut or tools to remove. I have seen a lot of complaints about the BORA P-Cap being too slippery to keep table top in place, so I have included both a SMOOTH and a KNURLED design. Rubber cabinet liner can be glued to the smooth cap, if you need both a better grip and a non-marring surface. Or you could just use them as bench cookies - you do you. Threads directly to my 6" extension design: https://www.thingiverse.com/thing:4761510 Design is an evolution of my prior threaded cap design: https://www.thingiverse.com/thing:4762874 Print files include both a metric and an imperial version, depending on preference and region availability. I THINK the BORA product is threaded for metric, so the metric cap can be screwed directly on to Centipede stand, without needing my 6" riser. Be sure you are downloading/printing the intended item! Metric: M12 x 1.75 (metric model not yet uploaded) Imperial: 1/2" x 13 (standard) Recommended print material is ABS/ASA Donations appreciated! Saving to cover the costs of a printer!
