Needle File Handle

youmagine

Install needle files with 3mm diameter shaft using interference fit by tapping them into place gently with a mallet and securely fastening them in a vise for ease of handling. The file was printed on an MP Mini at a layer height of 0.1325 millimeters, moving at a speed of 60 millimeters per second. To achieve maximum density, I utilized a 40 percent infill rate; however, I suspect that this may not significantly impact the final result, and it will likely be fully solid unless you choose to scale up the design.
