Amazon Soap bar cutter mod

I bought a wooden soap bar cutter for my wife for christmas from amazon https://amzn.to/3OBC5WT

The block used to set the width of the bar would twist and did not do its job.  I modeled this replacement bar holder which works much better.  version 2 is tall to press against the whole bar and version 3 is the exact size of the original with nubs to keep it straight.  Printed with support only for the nubs and a support blocker for the bolt hole.
