Skin for uhltimate OTF Fidget Knife 3 part knife

I like the simplicity of uhltimate's OTF knife, but found it a bit small to easily operate with my hand, so I remixed Dragon_Bane's OTF knife as a skin for uhltimate's OTF knife. If you have already printed uhltimate's OTF knife, this skin should fit it easily. I also remixed uhltimate's OTF knife for comfort and reliability (details below) I print all the parts in PLA. I recommend printing the skin on a smooth plate, flat faces down with tree supports, and all the knife parts with ironing on for all upper surfaces, for smoothness. All parts should press fit, you may want to print 3x2.5mm dowls for the skins and or gluing the two sides together
