Cut the number of available slots down to seven and added sections on each end
to accommodate screws for mounting. Measures 7-1/4" long and 3/4" high.
All modifications done with Tinkercad.

Note: Designed for smaller files. See https://www.thingiverse.com/thing:4605131 for handles that fit perfectly.
