Filing Jig For Needle Files and Full Size

When using my needle files post processing some of my 3D prints, I realized I wanted a way to be more consistent with the angles in play. A few quick measurements and a silly bit of time on Tinkercad later, sucess!

A 45 degree and 90 degree angle for both the needle file(3mm/.12inch) and full-size file (15mm/.9inch).

It's not fancy, but it was a good starting point at least for me. I hope it is at least a little helpful for someone else.

The version compatible with Gridfinity was made simply by using the slicer's “Add Part” menu option to add and line up a blank 3x3 bin from the Gridfinity Refined collection. ( https://www.printables.com/model/413761-gridfinity-refined )

I printed mine in Grey Elegoo PLA,

I used Gyroid infill at 15% with 2 walls and 0.2 layer height, basic settings.

No supports are used on my Elegoo Centauri Carbon for the Gridfinity ver.

It fits all of my needle files except one that is a much wider half-moon shape.

The full size file was based on the widest of the hand files in my kit.
