Yes, they look to be fine! - I did put a couple eyelets as washers either side of the spring. You don't need to, but I had loads left over and they fitted just nice. I'd forgotten I'd done that.... oops my apologies! :-)The wingnuts just have ordinary 3mm washers beneath them. The whole feeder sits proud off the back of the printer by a 3mm nuts width + a washer either side of it. On all four corners.<br><br>I used 3mm studs to mount the stepper. I should probably take some more pictures of the assembly...
You can see how the eyelet fits (one 4mm eyelet - not two) if you look at where the filament goes into the feeder. It should be a tight press fit into the feeder body. If not, you can glue it in place.
<p>Hi, The 4mm eyelet guides the filament into the bottom of the feeder so it doesn't rub against the material the feeder is printed from. I wouldn't use washers as they'll have a much sharper edge to them than the smooth eyelet does (which has a nice curve to it) Everything I used I put in the Bill of materials. :-) What bits are you missing?</p>
