Good morning folks! Hope we all had a good Christmas. I know this is a little late now Christmas is past us, but is toy is good for all holidays!!
What I came up with is a mechanical design for a toy/ornament that you can use and design your own themed "toys" to put on it for every holiday you can think about.
You can also ignore the way I used the belts (*rubber bands) and change the order or cross them over to create different spinning in both direction and speeds, as all the pullies are of different sizes.
I hope printing this ornament brings you joy, you can color the pieces (as my daughter did to one of the snowman), and have loads of fun playing with it.
Be gentle with the tabs when closing and opening the lid, they are thin and have a way of snapping... I've attached two different lids in this design, in case you wanted the mechanism to be visible, or enclosed, you don't have to print them both. You can check out the project files on onShape on this link: https://cad.onshape.com/documents/3b93d08c5b8d4fb45ea5cf83/w/a0ec5bc3f6a6eee7abeaa98b/e/ab234d554b5312d0f1596f0a?renderMode=0&uiState=65906cb772334c18f21742c2
Most of these STLs do need supports, I will split the files into "Recommended supports" and "No need supports".
All of these were printed with PLA, 0.4 nozzle, 0.2 layer height:
No need supports: Handle Crank.stl Handle Pully.stl Mini Pully.stl (print x 4). Snow Man Pully 1.stl Snow Man.stl Star Base.stl Tree Base.stl
Recommended supports: Lower Case Open.stl Lower Case.stl Snow Man Pully 2.stl Star.stl Tree.stl Upper Case.stl
