File Handle

Print with the hole side down with a brim. The print settings I used for mine in PETG is 4 perimeters and 15% infill and it feels plenty solid.

If you need a custom size handle, request it in the comments (in mm): depth of hole for the tang, narrowest dimensions of the tang, dimensions of the tang at the depth of tang hole measurement. I will parameterize the model if there is sufficient interest.
