Tired of needing to use screwdrivers and hex wrenches for your creations? Print these out of a durable material (I used PETG) and grab a screw and associated nut and make yourself a Toolless screw to make installation and removal a breeze! 

I recommend printing them in the orientation they were saved using organic/tree supports. Once you take it off the build plate you will likely have a support still stuck inside, you can simply use a hex wrench against a hard surface to pop that out and then put the nut in place and push against a hard surface. If you want to tighten it more than what your grip allows you can simply use pliers or in my case measuring calipers to hold the knob in place and prevent slippage to make it a more robust hold.

Due to the size of these I would recommend a 0.4 nozzle or smaller with a layer height of 0.2mm or smaller to get desirable results (the one pictured is an m3 printed in PETG with 3 walls 30% infill at 0.12 layer height on a 0.4 nozzle). Please feel free to comment if you have any issues and I can tweak the models or add more if necessary.
