I actually quite like my DIY spacebars. I originally bought some 2.25u spacebars off of AliExpress and they were not only soulless but also not particularly comfortable. So I took my time designing/printing/sanding some homemade ones. The really important step, for me, was sanding that edge of the spacebar against which my thumbs rest. That had to be smooth and curved. Next most important was to get many many layers of clearcoat on it. That gave it a finished feel.
Thanks! I custom designed and 3-D printed those 2.25u spacebars -- then I sanded, primered, and painted them. Painting required the application of dozens of tiny pieces of masking tape to get the checkered pattern. Then I put on six coats of clear lacquer to protect them from my grubby thumbs.
KBO-5000 build with custom 3-D printed tenting and bracket to hold the two halves at a fixed angle.

Anyway, fwiw, here's my .STL for it: 2.25u spacebar
