Filling in the blanks with missing parts

Hi there,

I am in the early stages of my build - there are certain parts either mentioned in the YouTube video, but aren’t in the BOM or the 3D model (or at least, I can’t find them). These are mostly small, for in the side rail assembly there is apparently a number of bearing retainers and lock nuts used to secure the bearings when under load, but it’s not clear what these are.

This might be obvious to people who build these sorts of things, but for a newbie I am not sure what I can substitute here.

It’s also frustrating having to wait another 2 weeks every time I realise I have mucked up an order from AliExpress :smiley:

I did find the locknuts at Aliexpress, if that helps. 1/2/4/6pcs 304 Stainless Steel Round Nut DIN981 Slotted Bearing Locking Precision Round Nut M10 M12 M15 M17 M20 M25 M30-M100 - AliExpress 13

Ahh, I see now there are bearing retainers in the zip file…

Run through the onshape file and cross check with the BOM on the website, once you make a list from these two reference points, you should have everything. I had to go back and forth but finally got it, I have asked Dejan to consider an update on the BOM.
