Retractable eraser case

The case was made to suit the Staedler eraser model that shows in one of the photos attached. The size of the eraser is 62.25 x 21.65 x 11.65 without paper sleeve. Other Staedler rubbers size 65 x 32 x 13 should fit in the inner sleeve as well but unfortunately I don't have other models to test them on. 

You can try scaling it to suit the size of the ones you have but bear in mind that the mechanism is quite already fragile. If you were to scale for narrower one and didn't work, please let me know so I could make a new size that suits yours.

I tested printing the model with Bambu PLA basic, Matte and PETG HF without any problem. Avoid using PLA Silk+ for the inner sleeve as the mechanism would easily break off and won't function properly(tested).

Assemble is pretty straight forward. slide the inner sleeve in the case, an eraser can be inserted either before or after sliding it in. Pop the cap on. 

I made the model for my kids, they seems to enjoy using it so I want to share with everyone here. This is my first publishing model so my apologies in advance if anything isn't as good as you expect. Hope you find it useful though ^_^
