Y-Axis belt tightener for the MK2.5

I had a loose Y-Axis belt, and tried to tighten it. I was having trouble, and since I also have a MK3S I realized that it had a superior way to hold the belts and tighten them. I printed the two pieces, put them on my MK2.5 and Oops. The pieces are not tall enough to hit the mechanical stop that the Y-Axis has on the MK2.5. 

So, has anyone printed a different piece that it tall enough to hit the switch? Should I try to move the stop a bit higher - closer to the heatbed frame - so that the part might hit it?

I modified my MK2.5 in that way that I built a solution similar to the Prusa Mini (see below)

I printed the parts in PETG with 3 perimeters and 40% Infill,

Ooooh. So you left the original piece, and made the end adjustable. That's not a bad idea. I will see if I can get the old piece with my shortened belt back together. Thanks.
