I bought this damaged baritone ukulele to repair and play, and after gluing up the cracks that it had in the top I found that it was still just a bit warped, causing the action to be a little low. I designed this replacement saddle that sits a couple of millimeters higher than the original. You can scale it right in your slicer to customize it for your instrument. It took a little sanding and filing around the bottoms where the brim had been to get a good fit, but it ended up working perfectly.  Print with 100% infill, or enough walls to make it solid. I used bone colored PLA plus.
