Large Pill Cutter

I needed a pill cutter that my wife could use. I looked on Makerworld but couldn't find one that would work long-term and at least enclose the razor blade to prevent accidental cutting. I printed it in PETG, but I am sure PLA is fine as well. The blade used is a regular-sized utility knife blade. I have also included a piece to cover the business end of the blade for installation. I might need to adjust clearances a little more. My first print held the blade nicely. The latest one still holds it, but looser than I would like. Let me know if you have a suggestion.
