When I was building the Bugatti aircraft, there is a very small part that attaches next to the instrument panel. It is a couple of control levers and is about 1/16th inch square. I whittled down the sprue connector and worked over the part and split the big single lever into two levers. (Big being relative the thickness was a little over 1/32 thick and 1/16 by 1/16) Anyway I noticed it was becoming a little loose while I was painting it.
Painted the parts and moved them over to the workbench from the spray booth. When I looked for it, the sprue had a stub and no part. Think flat pin head and you have the size. I ended up sweeping the floor and collected the dust in a dust bin and looked at it with magnification.
Yup, I found the part and it is on the model. I have a dark tile floor and no carpeting. Makes it easy to sweep up the plastic shavings.
