My first major project getting to learn 3D modelling. Its a pretty heavy remix of MacGyvers Sliced Human skull. Mostly for learning and just for fun. While my printer is tuned pretty good, and have made 4 so far without incident (no pics but a couple other colors) I still needed to do some light post-processing for each. Results will vary no doubt.
Insert (or remove) the pin from the top of the base piece through one hole then the other. Connecting the jaw and pin (and taking it apart) are a little tricky sometimes. I push them to one side or the other and you can bend the jaw just a little bit to get it on or off. I wanted it a bit tight so the jaw would hold open and closed.( see post processing)
Any questions don't be afraid to ask. Open to suggestions and re-remixes. I plan on making some overall improvements and other versions when I have the time.
If you don't see the pictures I uploaded, I put them in my "Makes" folder too
Used standard PLA settings on slic3r PE. I get the same results with Cura too. 215-210/60 C
I used extra perimeters. (at least 3). A brim will help for jaw and pin.
Infill shouldn't matter. Its a thin object and with an extra perimeter or two you can go from 0-100% if you wanted to. Use at least 10% to be safe.
(All of the little connection points are still holding up good with repeated use)
I printed the everything pretty much in the orientation that they are in the file, which used a lot of support I'm afraid, but the results were great. The jaw pin is printed horizontally and at 100% infill for more strength.
I printed the parts individually, except the lobes I did together. Total combined print time of all parts with my settings was a little under a day.
Jaw pin needs a little sanding or trimming after being printed horizontally to get it round again. The pins/flaps/things whatever connecting all the parts as well as any seams between parts may also need some sanding or trimming.
If the jaw moves around too loosely, use a little bit of hot glue (or nail polish or a thin layer of something else may work) in the little groove where the jaw hinges on the bottom part of the base piece. just do it quick while its hot, press the jaw in so the glue takes the shape.
A little hot glue where jaw and pin connect. (if jaw is too loose)
