Ergonomic File Handle

thingiverse

Face it, filing plastic models is a tedious fact of life when you work with 3D printing technology. Your hand may end up resembling a withered claw after doing this kind of work repeatedly. This product is an ergonomic handle for small "hobby" or needle files which are commonly used to finish off 3D-printed models. The cross-section features a Relaux triangle that is slightly sculpted to provide a pencil-style grip allowing for fine control and reduced fatigue. These handles are designed to fit needle files with a cylindrical shank three millimeters in diameter. Examples include the Nicholson 5-1/2-in assorted hobby-craft mini-file set from Home Depot, and the six-piece needle file carded by length available on Amazon. You can also scale these handles to fit other sizes and types of files. In addition to the file handles, a matching stand is provided as well. This stand holds the files securely and makes them easy to access. A center cavity in the stand can be used to store another tool which you are always reaching for such as a pair of tweezers. I hope that someone will find these useful and print them out with their 3D printer, then upload a few photos. I am not very skilled at being a hand model unfortunately. Instructions Both the file handles and the stands should be printed in the given orientations. The file handle model features a thin disk that promotes better adhesion to the build surface; it is easy to remove with a knife or a machete. No supports should be used when printing either the file handle or base. The handles are assembled onto the files using a press fit. You get the best results by clamping the cutting surface of the file vertically between two pieces of wood in a vise, and hammering the handle down onto the file. If you have access to a propane torch, assembly can be made much easier by heating up the file shank but be careful not to anneal the cutting edges.
