“Argh! They got me! I did know at one stage that these are for 2020 extrusions not the 1515 which this shop stocks, but forgot and ordered them when I ran out in the middle of a project. Pimoroni should standardise on 1515 which fits well with the scale of robotics and machines best built with the rest of the mechanical portfolio. I had to import the 1515 version of this from China (on right in photo).”
