Olfa-L5-AL Boxcutter Replacement Thumbgrip

Replacement Thumbgrip for Olfa L5-Al Box Cutter Knife. This knife has been a trusty workhorse for nine years, but its original thumb grip was woefully designed - prone to breaking at the worst possible moment. I've found that printing my own replacement at 0.2mm layer thickness and 25% infill provides a sturdy solution. To avoid any issues, it's essential not to use support material, as this can gum up the grooves and interfere with the knife's center catch. If you find that the thumb grip doesn't fit comfortably in your hand, don't worry - the customizer feature allows you to make adjustments until it feels just right.
