Parametric Shaun to "fit them all" (toilet paper roll sizes - 36 mm roll included for most EU countries)

This is a really a awesome model by ErdosNumber4 and a great remix by MV!

It will look very nice in your toilets and certainly much better than the “standard” toilet paper roll in a closet or hanging around.

I was not expecting to, but it looks like there is no standardization of paper role size around the world and 40 mm size from MV or ErdosNumber4 version was by far too large for my paper rolls (in France at least).
After a few tries, it seems that 36 mm was the perfect fit for me.

The 36mm final version includes all the white parts you need and are correctly positioned with the required supports in the .3mf file “shaun_36_mm_dia”.

I also modified the black part for the eyes and the feet, reducing them to 98% so they could fit better (I really struggled with the initial model do insert the black part of the eye inside the white part and broke a couple of feet attaching them to the base, so this version should be easier for assembly). Everything you need in black is in this file (and the white part in the other files). I also added a few chamfers to the each tube to make them fit / insert easily.

I also added the 39mm size which I produced through my trials.

In the process of finding the right size for my paper roll, I used Fusion 360 to make it parametric (it took me 3 trials to get it right but as it was parametric I could adjust the size in a few seconds) so I wanted to share this Fusion file so other people around the world could enjoy this nice print whatever roll size they have!

To change the size of the roll :

+ Import the file Shaun_parametric.f3d in Fusion. 

+ In the timeline edit Sketch1 to change the diameter (36 mm for me) to your size. 
This would be the size of your toilet paper role hole (for the Tube1 where you attached Shaun's head).
This tube1 has a 3 mm wall and will be automatically adjusted (it's a formula) so you just have to exit the sketch and you're done.

FYI - The second tube (with Shaun's tail) will be automatically adjusted as well to your size roll. To make things clear, if you have a roll size of 32 mm for instance (instead of 36mm for me), you just have to change in the sketch 36mm by 32mm. Automatically the inner circle of the tube1 will be changed to 29mm (to preserve a 3 mm wall) and the diameter of the Tube2 will be changed to 28.9mm (as I use a 0.1 mm tolerance for Tube1 to fit into Tube2 which is perfect for me but if needed you could change the tolerance in sketch2 formula but it should not be necessary). 

+ In bodies export each body as a mesh (right click “save as a mesh”)
you will end up with 2 .stl or .3mf files (something like body1 and body2).

+ Finally, you will have to add Shaun's tail to the tube generated by Fusion.
For that import Shaun tail file to your body2 file. Merge both objects.
Center them the way you like and increase the height of the tail by 40 mm (it is very easy to do by adding these 40mm to the Z value of Shaun_ass object in the merge file. To be clearer the Z value should be 59.22mm).

That's it! It looks a little bit complex but it is really simple as importing fusion file, changing one value in the sketch file, exporting the tubes and merging the tail. After a couple of trials it was a 3-minute process (OK it may take 10 minutes the first time but you will get your model perfectly sized for your role :).

Hope you enjoyed this parametric version. Please let me know if you have questions !
