Metric screw measuring device - M2/2.5/3/4/5 4-50mm

prusaprinters

<p>Quickly sort and measure metric screws and bolts in sizes ranging from M2, M2.5, M3, M4, or M5 with lengths from 4mm to 50mm. Screw diameter sizing is a simple go/no-go clearance check which is faster than threading in a screw. Note that this doesn't tell you anything about screw pitch, but all of my metric stuff is standard coarse thread so I'm okay with this. If you want to confirm the exact thread, check out <a href="h/sneaks">sneaks'</a> <a href="https://www.thingiverse.com/thing:4056498">original design with threaded inserts</a> or check out <a href="/registeredthing">registeredthing's</a> <a href="https://www.thingiverse.com/thing:4057284">remix with nuts as inserts</a>.</p> <p><em>Update 28 Feb 2020:</em> Per a request I have uploaded a version with no keychain loop or back text. This is available under Metric screw measuring device-sanitized.stl in the Thing files.</p> <h3> Note about standard lengths</h3> <p>I've gotten several comments about the ISO standard lengths and how it goes up in 5mm increments past 20mm and so forth, and several requests to redo this with the standard lengths. There are already several <a href="https://www.thingiverse.com/thing:4154091/remixes">remixes</a> which have done exactly that. The problem is not every bolt and screw complies with standards. I have right here an M8x22, an M6x15, and an M4x13. If I had the markings on the "standard" lengths, it would be difficult to determine the exact length of those. Because of this, I have no plans to change Sneak's excellent original design and don't find it that hard to read. If you are certain you'll always deal with bolts which conform to the standards, then check out the remixes.</p> <h3>Print instructions</h3><h3>Category: Hand Tools Summary</h3> <p>Quickly sort and measure metric screws and bolts in sizes ranging from M2, M2.5, M3, M4, or M5 with lengths from 4mm to 50mm.
