Repeatabale Torque Settings - adjustable - Tool - Wernch -Driver





Description
Tunable torque wrench by ChipCE (https://www.thingiverse.com/thing:4744378) inspired this model, I did however start from scratch. The fact that his model uses a "yellow printer spring" is great, we all have spare of those, but I have not tuned to get to that so far.
The mensioned tool I liked better than most others on the net, but it has one big flaw in my opinion. Any downward pressure into the screw will nulify the calibrasion and deliver vairable results. Since pressing down into the screw comes as natural as breathing for me, this was an issue. I am hoping ChipCE implements my alterations into his model, the yellow spring thing would be great.
My model is an attempt to elimanated the pressure issue and deliver REPEATABLE results. I needed to tighten all ten M3 screws om several MGN9 rails at the same torque. That helps to keep the rail flat and straight, redusing friction and binding. I only printed one so far and it needs some refinement and tuning probably, but the results was good for me even without calibration. It seems to deliver the same setting time and time again.
PS: my hex bit collection is quite big and different bits do fit tighter or looser for the "well used" ones. If tou find its too tight just do a six sided cut in the middle there, or when the toolhead lifts, force it into the hot plastic and leave the part to cool. As always, if in doubt, use a hammer, but results may vary.
