Extractor Hood Filter (iD: 30mm; oD: 172mm)

The problem

What common problem is shared by extractor hoods and printers? 

A lack of standardization and interoperability of the disposables! 
Parts fitting your specific machine are expensive or hard to find!

This is a custom extractor hood filter for less than 3€, that perfectly fits!

My solution

I created a filter fitting the bayonet joint as shown in the picture.

The outer dimensions of my filter is mainly 172 mm, see the details:

I designed this filter to consist of four parts:

1. The bottom part
2. A universal flat filter fleece, to seperate the fat.
3. Char coal pellets to extract fumes and residual smell.
4. A top part to hold everything together

How to print and assemble

1. Print the two parts from PLA:
   1. Support is only needed for the three little parts in the middle. 
   2. Printed with 0,24mm layer height
2. Use the top part as a stencil and cut out the universal fat filter paper.
3. Insert some charcoal pellets.
4. Glue the top part in place with PLA glue (e.g. UHU Allplast)

And your done: Place it on the bayonet and rotate it into position.

Design history

As mentioned: Those filter parts are not standardized… Therefore I neede some iterations to get my dimensions right. Have a glimpse:
