UPDATE 3/31/2023: I revised this design to make all the vectors connect and should be minimum issues when using a FDM/FFF printer.

Suggest using these slicer settings below that made the bars turn out better. Note, these settings are from Cura by Ultimaker:

At 240% on all X-Y-Z axis's is what I resize it to for printing that gives a relative decent size (L: 3-5/8\", W: 3-9/16\", H: 3/8\") for a small hand-size print. See pictures for comparison of the older version and newer version from these settings:

Print Quality: Standard

Monotonic Top/Bottom Order: YES

Infill: 15%-20%

Infill Pattern: Line

Optimize Wall Printing Order: YES

Print Wall Ordering: Outside to Inside

Print Top/Bottom: Top Thickness - 1.0 mm

Top Layers - 5 layers

Bottom Layers - 3-5 Layers

Print Speed: Outer Wall - 50 mm/s

Inner Wall - 70 mm/s

Infill: - 70 mm/s

Top/Bottom: 50 mm/s

This was created from the actual size of a collar version bars, so it is very small on the print bed which you will have to scale to higher.

Shoutout to all my officers holding down the double bars but not causing a double standard!
