UKS (Utility Knife Slider)

thingiverse

This is my design of a slim, and yet very usable utility blade. I have mine stored in my wallet, but you could slip one of these anywhere. To get the proper tolerances YOU MUST print with a layer height of 0.12mm with an initial layer height of 0.16 as well as a hole horizontal expansion of 0.2mm. If the tab on the smaller piece is getting fused to the outer wall up the hole horizontal expansion to 0.25-0.3mm, or if it seems too large bump that value down to to zero. I cannot guarantee any success without using the previously mentioned settings as they are what I designed the parts to be printed with. I will say the tolerances are tight and are tuned to my Ender 3. If the tolerances are too small for your machine I would recommend first testing to see how the utility blade sits into the inner piece, if it is nice and snug scale up the outer piece 2-3%. If not scale both up until the utility blade can be fit it without any wobbling. Also there is a small notch in the bottom of the inner piece and the utility blade must be inserted into this notch first before pressing it in to the top. Any suggestions are welcome!
