Fully 3D-Printed Torque Meter With Dial Indicator

Before you proceed to assemble the model, please read the assembly and printing guide, also read the information here in the description of the model. I was curious if you could make a fully 3D printable torque meter, so I tried to design one and this is what I came up with. It can be used to measure smaller torques, good if you don't want to spend $70 on a digital off-the-shelf one when you know that you're going to rarely use it. It can measure torque up to around 2Nm in both directions (when printed in PLA). The measurement error when printed in Bambu Lab PLA Basic is ~0.045Nm for torque under 1.5Nm and ~0.1Nm for torque over 1.5Nm - you can tune the max torque and accuracy by changing the material that you use to print the “torque shaft” part. I've made the labels of the scale editable in Bambu Studio, so if you use different materials, you can change them according to your needs. All reference and test measurements have been done using Vevor DSM1-100008B Digital Torque
