Sandfilter Pump Part / Pool Pump

thingiverse

the SCAD thumbnail looks broken as the 3d object is to detailed. the limit has to be increased if you need to adapt it. This is a Part that is used inside a sandfilter (for pools). It lets water through and blocks sand (with minimum particle size of 0.75 mm). In my Sandfilter a part similar to this one broke and i couldnt find a replacement in shops. So i created this and saved some time & money searching for a replacement part and waiting for it (if a part would have been available). the pipe it connects to can be customized in the scad file. i've put it in my pool pump and it seems to work.. i think i should have put more holes into it as the flow rate has decreased a bit.
