Flexible Allie and Flexible T-Rex

Please don’t download all the (STL) design files at one time.

Download the first dinosaur design and then shut down your browser while you slice and start the print. Then you can fire up your browser and navigate back in to download another model.  By shutting down your browser between downloads, I get credit for all downloads without posting separate models and repeating instructions.

Printing

Generally I use a 0.25mm layer height and put about 1mm of plastic on the outside surfaces as a shell.  Since my printer has a 0.5mm nozzle I use 2 vertical shells and 4 horizontal top and bottom layers.  I set a honeycomb fill pattern with a 15% honeycomb fill density.  Support isn’t needed when printing the parts for the flexible dinosaurs.

I have not had problems printing these designs with ABS.  I’ve not tried PLA.  But, I did have problems printing with ASA.  The partially printed coupling links between sections curled up and acted rubbery as the extruder added plastic.  They eventually caught the hot end and shifted a stepping motor count and the remaining print layers.  The cure is described in the Prusa Research Forum.  I.e. slow down the print speed and lower the bed temperature if adhesion will allow it.

Enjoy !!!
