Metric Bolt Size Reference for Thing-O-Matic Assembly

thingiverse

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. Instructions Pick your source: The LaserCutCoasterReference_Metric.dxf was sized to fit on the "coaster" cut-out in the center of the laser-cut fan filter mount. The ToMboltmatch_4up_v2.pdf should print four laser-cut reference coasters on an 8.5"x11" sheet of paper. The LaserPrintReference_Metric.dxf was sized to fit comfortably on a 3"x5" or A7 index card sized piece of paper or label. The ToMboltmatch_8up.pdf should print eight of laser-print reference cards on an 8.5"x11" sheet of paper. Test-print the source. Confirm with a ruler that the dimensions (in mm) are precisely 1:1 scale. If not, adjust your printer driver's scale accordingly and re-print. Assemble your Thing-O-Matic.
