Dual Breadboar holder with 5 banana plugs

I based this off of the design by JRodrigo although I just used his measurement for the width. I liked his design but I already had banana plugs.

I based it off using these plugs https://www.amazon.ca/gp/product/B07D6JGQFG/ref=ppx_yo_dt_b_asin_title_o00__o00_s00?ie=UTF8&psc=1

no modification required I tossed away much of the hardware and thread the plug directly into the pla. I needed to use a wrench to screw them in, don't use just the top of the plug or it will likely break.
