Really nice chapstick. :D
I modeled the chapstick in PTC/Onshape.
It is three separate parts and to scale. 68mm long 16mm DIA. The cap, body, and chapstick.
I rendered it in Blender and I have posted the native files if you wish to change anyting.
Rendered images are from Onshapes free software for examples only.
It was not set up for 3D printing but it could be printed if you like.
