We did not have the Lego pieces necessary to create JK Brickworks Lego Frog, so I designed, 3D printed and assembled this version for our grandkids.
The joints are ball and socket with .2mm clearances and simply snap together. There are 8 unique 3D printed pieces (10 total) that create the frog, all pieces print without support and, for me at least, required no filing, sanding or other clean up prior to assembly.
Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.8.0, and 3D printed in PLA on an Ultimaker 3+ Extended and on Ultimaker S5s.
Materials and methods
I 3D printed all parts at .1mm layer height with 20% infill and no supports
I 3D printed two of each eye part (Eye, Black.stl, Eye, White.stl) and one each of the remaining parts.
Prior to assembly, I test fitted and trimmed, filed, drilled, sanded, etc. all parts as necessary for smooth movement of moving surfaces, and tight fit for non moving surfaces. Depending on your slicer, printer, printer settings and the colors you chose, more or less trimming, filing, drilling and/or sanding may be required to successfully recreate this model. I carefully filed all edges that contacted the build plate to make absolutely certain that all build plate "ooze" is removed and that all edges are smooth using small jewelers files and plenty of patience.
After part preparation, I assembled the frog as shown in the video.
And that is how I 3D printed and assembled "A 3D Printed Simple Mechanical Frog".
I hope you enjoyed it!
