Keychain knife with a button 3D for print

I have pr...inted many times the original keychain for gifts to friends. I also used it in my work, which allowed me to identify some shortcomings and make my own changes.
Now it is possible to open the blade with one hand.
For more precise positioning, the slider are built on a groove-spike system. - This option has a fairly good fixation in the open position and now it is more convenient to blade update.
The size is even smaller.
The size tolerances are small, so for fine-tuning the parts, it will be useful to remove possible printing artifacts and work a little with a flat needle file in the grooves. It will be better to lightly lubricate the friction points with mineral oil or silicone grease (just do not overdo it, so that the grease does not get on the outside). Before assembling, rub the moving parts and check the tightness of the fit.
To put the button in place, you need apply pressure from the back side with force on the ledge the spring.

MIK BAR3d model description
This is a remix of the Talon V2 knife by HallPrecision. The guys from HallPrecision did a great job on the design. Many thanks to everyone.I have pr...inted many times the original keychain for gifts to friends. I also used it in my work, which allowed me to identify some shortcomings and make my own changes.
