X-Acto retractable Blade Holder

2/5/2025 Updated blade holder for better latching of slider.
I liked the idea of a retractable X-acto blade holder as found at: www.thingiverse.com/thing:4616181. But, I felt that it needed a bit of revision to make it more stable and reliable.

Using PETG filament, the blade holder was built with 100% infill and the handle with 30% at a print speed of 20mm/sec.

Remember to make sure that the blade holder moves smoothly and snaps into the notches before glueing the handle together. Also, I recommend puting the glue on the right handle side to avoid getting any glue on the blade holder.

The blade (X-Acto #11) is retained via a short length of 1.75mm filament that is cut flush with the sides of the holder.
