Fan Filter Extraction Case Housing - Easy to change filter

I created this so I can have a fan filter, where the filter is easy to remove, so that it can be replaced or cleaned. The filter is pushed in to the inner slider and then the slider is inserted in to the main filter housing.

It's designed to be used with filter material obtained from 'Banggood' = https://www.banggood.com/Aquarium-Biochemical-Cotton-Filter-Foam-Fish-Tank-Sponge-50x50x2_5cm-p-939713.html?rmmds=myorder
