Roll channel fixes summary

here is a summary of all of the below so you don't have to scroll over all my old post for the roll channel:

1. in step 24 it should be locknut and not regular nut

2. there is an alternate part 10, in the headline it says X2 but in the description it says QTY 1

3. both for part 10 and 15 , the new orientation says 100% infill but the original one says 40%?

which is correct?

4. parts 6 and 7 say FRME instead of FRAME

also connected to the roll channel:

are the fusion files for the post supports: https://www.737diysim.com/dual-737-control-frame-build-guide

available,

I could only get 40mm instead of 38mm steel and the PVC piping here has an ID of 72mm....

so I need to update the parts. - I imagine in the UK, you can also get only these standard measurements?
