Got cheap ergo grips, too short, modeled and printed extension, wrapped in leather

I got that pair of cheap ergo grips, planned to remove the PU wrapping to replace by real leather.
Didn't check length, grips were very short, shorter than my palms.
Modeled an extension tube using Shaper3D, printed in PLA. That went well with only 2 iterations, mainly for adjusting tolerance.
Wrapped in leftover leather from Hermès (there's a Hermès factory nearby) and saddle stitched it on the grips. It's very soft and resistant, turned out better that I thought originally.
