Be it infuriating DIY furniture or fiddly construction projects, sometimes you need a tool that can fit places most tools aren't meant to. Or sometimes you don't have the right tool at home, but you do have a 3D printer.

These socket shaped tools fit 10mm hex bolts, can fit in places most tools can't and even in PLA can last a DIY project (if not, just print another). And when 3D printed they can even be cut or shaved down if needed.

But these aren't just 10mm tools. Need a 12mm socket? Print it at 120%. Need a 3/8" socket? Print at 87.31%. These may not be precision tools, but they are get the job done tools when a 3D print is your only option.

These are a remix of a 10mm Socket piece intended to be used with a standard Wrench originally by RLerner “10mm Socket (Hero of Men!)”, now adapted to only need your fingers, so they can be smaller, fit more places, be easily manipulated and require no additional tools.

They saved me hours of frustration putting together a new Bed that had over 50 nuts and bolts, wrenching some tight or just holding a nut tight with as little as a single finger whilst tightening a bolt, in hard to reach places. I hope they save you from frustration too.

Print settings

Based on Orca Slicer whilst using generic PLA

Default Elegoo CC2 (Centauri Carbon 2) 0.4 Nozzle settings worked for me.

Default 2.0 layer height

With Solid Infil (Strength Tab > Advanced > Insert Solid Layers = “1#1”, e.g. for every 1 layers 1 solid layer)

At 100% scale…

22min~ print time for the paddle Socket Wrench.

28min~ print time for the spoke Socket Wrench.

These may not result in the most precise results for Imperial measurements, but hopefully they're are close enough to help.
