That's a pain in the rear. In contrast I just got a new 3D printer from Prusa. The instructions were terrific, except that they were on line - no printed manual - so I had to take the laptop to the shop. But it was all good otherwise. Each step had its own little Zip Lock baggie with the fasteners for that step. There were around 40 baggies and EVERY ONE had exactly what it was supposed to have. The instructions listed the length of every screw, which was handy because there's not much difference between a 3x8mm and a 3x10mm, so the digital caliper was handy. And then there was another larger baggie with spares of everything, even the little magnets for the filament sensor. I had to get into it a couple of times, but only when I dropped something and couldn't find it right away. That's the way all DIY assembly projects should be done!
