3D model description
The second model in my collection of cute lucky animals. Tap on its head and it will wave to you for up to 1-2 minutes.
As with all my designs, I went through multiple iterations to perfect the mechanism and the printability of the model without any support structures. All you need is a good bed adhesion and good cooling for some clean overhangs.
No assembly is required!
The integrated compliant mechanism and printed spring allow for a frictionless design with big tolerances which should make it possible to print this on almost any FDM printer. SLA might work as well although it is not specifically designed for it.
This model can hold coins within a size of 23 – 26 mm (0,9 - 1,02 inches) which makes this model great as a coin saver for shopping carts. Alternatively, a printed weight can be inserted if you don't have fitting coins.
It’s also fun to put the model on your car's dashboard as the chickens will start waving in sync with the movement of your car while driving.
If you want, check out the third model of this collection :)
3D printing settings
IMPORTANT: Make sure that the springs will be printed by checking the slicer preview. Here are some slicer-specific settings to make sure that the spring will turn out correctly.
For all Slicers
I would not use a brim for the bed adhesion as it will be hard to remove from the spring.
Print Settings > Advanced > Slicing > Slice gap closing radius > set the value to 0 mm
(If you are using a version older than PrusaSlicer 2.5 go to Print Settings >Layers and perimeters > Quality > Detect thin walls > activate it)
No special settings required
(If you are using a version older than Cura 5.0 go to Walls > Print Thin Walls > activate it)
(Advanced settings > Quality > Precision > Slice gap closing radius > Set to 0 mm
(Advanced settings > Strength > Walls > Detect thin walls > Activate
This model is designed for a 0.4 mm nozzle/linewidth. If you have a bigger or smaller nozzle installed on your printer I recommend you scale the model up or down accordingly:
0.3 mm Nozzle => 75 % Scale
0.4 mm Nozzle => 100 % Scale
0.5 mm Nozzle => 125 % Scale
0.6 mm Nozzle => 150 % Scale
0.7 mm Nozzle => 175 % Scale
The model is designed to be printed on its back as it comes with the file. Printing in any other orientation will cause the springs to fail.
Supportfree design. No support is required.
A good print bed adhesion will guarantee a successful print, so make sure everything is properly-leveled and maybe apply a spray adhesive if your filament requires that.
At 100% scale, it prints in roughly 5 hours with 50 g of material.
Set the cooling to a high value.
Be careful when removing the model from the build plate.
If you have any issues with stringing its best to remove the strings by hand to increase the swing time of the pendulum.
