Center Finder -extended

I like the design, but I needed to find the center of wider boards, so I hacked up the cross braces to make them longer in Tinkercad. I've included 2 set, both longer than the originals. This is the first time I've ever worked with Tinkercad, or any type or 3d modelling, so I hope I got it right. Please let me know if I've screwed it up.
