Parametric Mini Fishtank Filter System

I had this mini aquarium and it's hard to find water filter for it's size, so I had this mini water pump from abandoned project and deside to made my own filter. This fits with mini submersible water pump, you can find in aliexpress or other marketplace with the price just around $1. Of course since it is parametric, you can modify any parameter using openscad. The available parameter are :
inerd : iner diameter of the pipe, should match the outer diameter of your pump's pipe
outerd : outer diameter of the pipe, just add a couple milimeter from your inerd, this also define the thickness of your printout
pipelength : the length of the pipe from the pump to the filter bay, set this close to the depth of your tank and make sure your pump powerfull enough to push water to the top
length : the length of the pipe inside the filter bay, this also affect the height of your filter bay
please use as you wish and modify as you please, let me know if you enjoy this design.
