Aaahh. So the slots for the belt are pretty wide. Hard to judge the scale.
Yup. Especially if you shorten the lever or move the fulcrum up to get more range.
Yup. I tried to design it so that the one design will work for all three belts on the Shapeoko 3. There doesnt need to be a left one and a right one. It might also work for the Shapeoko 4 as I think it uses the same profiles and the belts general locations are the same, just wider.

Resurrection!
So, I downloaded Neil’s files from Thingiverse…
First time printing with PETG on my Ender 3 and it went well!
I mounted the tensioner base on the steel frame and used it as a guide.
With some Tap Magic and these cheap Uxcell 3.5mm Cobalt drill bits, I drilled three through holes across the slot.
I then removed the tensioner base and used the cordless drill side-to-side with the bit through each hole in attempt to remove the most material.
With the trusty C3D #102 end mill and my Dremel I removed the rest then hit it with a file or grinding stone in the Dremel.
I slotted the frames only at one end of each belt. These pictures are of the better looking slot out of the three.
I took the opportunity to install these steel core belts that I had ordered a long time ago when they were still the rage.
It’s not the first time and I imagine it won’t be the last time I say it either… thanks @neilferreri
