Dovetail InMoov test

thingiverse

Testing dovetail design for fit and consistency. Adapted from InMoov torso plates. Three models here, one of the assembly others of components. Now there's two more models to print and the .step model that they were derived from. Not being happy with the gaps at the sides of the dovetails when assembled (caused by flexing) or the gaps along the main surface, I've made a couple of variations that I think give a better joint without so much distortion of the model. There are two different pattern dovetails on the model. By inverting one part to the other it is possible to test the joints individually. This true for the original files too. Using a parametric CAD program (FreeCAD for example) the .step file can be modified to other dimensions for more experimentation. Print Settings Printer: Print-Rite DIY 3D Printer Rafts: No Supports: No Resolution: 0.2 layers Infill: 20% Notes: This is a small enough model to experiment with different settings for the printer to get best results for printing out the main parts of the robot. How I Designed This Found that the dovetails on the Torso plates varied from place to place. Even on the equivalent place on the other side of the vertical centre line. These are a nice firm fit without too much effort to assemble in PLA. I'm interested to know how others find these to print and assemble.
