Another leg part. The distance between the 25mm tubes is 3mm. The "shells" are 1.5mm thick, so that at least 3 parts for one leg are the same.
I don't want any end-switches on the legs at this point, because the are usefull on the moving parts. If I want to limit the working area, I can do it with a simple clamp.
I could be totally wrong here, but I don't have a plan... Just making it up as I go...
P.S. the red part is identical to the yellow parts.
