Here is a set of Frames one can print for the FlipBoks - Flipbook Machine by evets17 - MakerWorld flipbook machine I designed. Note: these are just the 24 frames for a FlipBoks' animation. Go the FlipBoks listing for printing the core parts.
This is an example of a fully 3D printed approach to creating a FlipBoks animation. This one is of a Cat running through a field.
I call this a Half Frame approach, because we only print our animation on one side of the cards. This approach allows us to do multi-color printing by doing color changes at certain heights.
I print these with .2 layer height and do color changes as follows (technically you can use whatever colors you want, these are colors I used that match images on this listing):
Start with Blue
At layer 4 switch to Green
At layer 5 switch to White
At layer 6 switch to Black
The cards each have a number in lower left that indicates the frame number, so can add the frames in right order.
For this one, I used an open source Pencil2D Animation | Open Source animation software to create the 24 frames (png). Then converted those images to SVGs and loaded into Fusion 360 to make the card models. On my main FlipBoks - Flipbook Machine by evets17 - MakerWorld listing, I include an .f3d (Fusion 360 project) that can aid in creating your own animations.
