Not sure how I will progress from there, but this is all a step by step, print small and go on theme. These parts are almost 20cms, so I print them one by one diagonally. The holes are for later stiffness by adding parts.
[update] 3hours later - first leg is printed and came out just fine, check the new project picture :) second one just started and I hope there is enough plastic on the spool to get at least this part done and then I go for yellow. No Idea why I didn't go with white and blue in the first place.
