I’ll dig out the files and figure out how to share them soon, bear with me!
I don’t think it has any impact being only 3 threads, it is still tight. I did see a tiny bit of flex in the tallest one but I don’t know the exact source of it. PLA is pretty stiff and I burned up a whole kg printing all four.
I put my part of the cut pile together today, came out nice. The spots either side of the tabs were burnt from the machine stopping to raise and lower the bit either side of the tab, I used krabzcam, I’ll have to see what I can change to prevent those witness marks in the future. The slots I cut to put the steps into the sides were quite undersized, so for any future tab/slot things I’ll do some testing first to dial in the fitment.
One happy toddler who can now get into more things that she shouldn’t be!
