Trofast Rails for Harbor Freight Storage Case

I designed from the ground up rails for the IKEA Trofast frame.  I got the inspiration from here.  The .stl rails linked from that post would have worked but I decided against it as they wasted too much filament and made you drill new holes or use wood screws.  I wanted to use the existing holes and was able to with the use of M4×10 threaded hex inserts and M4×16 countersunk screws.  Further inspiration from Rails to slide Stanley organizer into IKEA TROFAST shelf for the overall look of the rail.  I was able to measure and design these rails for the frame in fusion360 and I will include the .f3d file for others to change and/or improve upon.

Installation is easy and straightforward.  You print out the three pieces and assemble from the bottom up. The holes are mirrored on the Trofast so you would print each section twice, no need to mirror them in your slicer. The rails mesh together using dovetail cutouts.  In order to allow the use of the existing holes I did have to have a hole along the bottom bottom rail .  I have included a plug for this to be super glued into the rail to prevent any snagging or catching of the case.  

This was printed on a 350mm bed printer with 0.4 nozzle and the default 0.02mm Layer Height with PLA.  Unfortunately I am not sure how to cut it to fit smaller print beds.  I have included the .f3d file in case you would like to break it up to smaller parts for smaller beds.
