Whether it's frustrating DIY furniture or tedious construction projects, sometimes you need a tool that can reach into those tight spaces where most tools can't reach. Or maybe you just don't have the right tools at home, but you happen to have a 3D printer.

These sleeve-shaped tools can fit 10mm hexagonal bolts and easily reach corners that are hard to access with many conventional tools. Even if they are printed with PLA material, they can withstand an entire DIY project

However, these are not just 10-millimeter tools. Want a 12-millimeter socket? Then print it at a 120% scale; need a 3/8-inch socket? Then print it at an 87.31% scale. Although they may not be precision tools, they can indeed "get the job done" when 3D printing is your only option.

These tools are actually a redesign of the 10-millimeter socket designed by the original author, RLerner. They were originally designed to be used with standard wrenches, but now, after being adjusted, they can be operated with just your fingers. They are smaller in size, have a wider range of applications, and are easy to control, completely eliminating the need for additional tools.

When assembling a new bed frame with more than 50 nuts and bolts, they saved me hours of frustration: some screws were very tight, some could only be held in place with one finger, and I had to complete the fastening work in those hard-to-reach corners. I hope they can also help you avoid similar frustrations.

Print settings

Based on the Orca slicing software, using universal PLA materials

By default, it uses the Elegoo CC2

The default layer height is 2.0 millimeters.

Set the filling density to solid filling

When printing at a 100% scale...

The printing time of the paddle-type socket wrench is about 22 minutes.

The printing time of the spoke-type socket wrench is about 28 minutes.

Conversion table of scaling ratio

These conversions may not achieve the highest accuracy of imperial units, but hopefully they will be close enough to be practical.
