Open Manufacturing - (How to Build 30 (SERB) Kits)

Step 11 Nut and Bolts

Envelope #1 (3mm Hardware) - if you are counting each item one by one this envelope is painful to fill. Because of this we purchased an old laboratory scale and now measure by weight (ensuring a twenty percent safety margin, we don't want anyone being short a washer). Add a couple of acrylic funnels and envelope filling becomes quick and painless.

Envelope #2 (8mm Hardware) - With only a couple of large items this envelope fills quickly
