Metric Bolt Size Reference for Thing-O-Matic Assembly

Keeping track of the subtle difference between M3 x 10mm vs M3 x 12mm can be a challenge on the best of days. Accidentally mix them up and you're occupied for the next hour fumbling through the pile with a ruler for the closest match.

Save yourself some grief and print off one (or more) of these reference cards to assist with your Thing-O-Matic assembly!

They should cover all the bolt sizes used in the Thing-O-Matic itself, the Automated Build Platform (V2) and Plastruder MK5.
