Allpa Bilgepump Filter

I decided to make a filterscreen for a small Allpa bilge pump. This small pump cannot handle the small twigs and leaves that fall inside the boat. The filter that comes with the pump has rather big openings. This model was put together with minimal trimming and shaving. That said, next time I would make/try some small improvements. 

Materials

• PLA, PETG 
• 4pcs 4x2 magnets
• Edge trimmer / knife

Remarks

• This is my first fusion 3d project. The raw f3d file is free to download. 
• If I need to reprint this filter I would make some minor improvements. As it stands now, the model came out fine thought it needed some small trimming to get everything nicely fitting together. See also red circle in attached picture.
• If I need to reprint this I would try to print the frame in PETG. Then the filter mesh (PLA) can be shaped to the frame in a bath of hot water. 
• The flat mesh was shortened 0.5mm. Originally I needed to trim the mesh somewhat.

Shaping the mesh

I heated the printbed to 70 degrees. PLA gets really flexible that way. I used the outside of one of the frames as a guide to shape the mesh. Even thought the shape will be matched to the ‘outside’ of frame I managed to squeeze it in without to much trouble. Only some trimming at the end (I removed 0.5mm from the flat mesh so less trimming is necessary next time)

Magnets

I used 4 magnets to keep the frame together and sticking to the hull (steel in my case). Size: 4x2mm.

Good luck. Feedback is always welcomed.
