Hi - I don't create threads often these days and this is not overly interesting....
I feed frozen food often, Ocean Nutrition Formula Two for example.
About 30 minutes after feeding, the skimmer stinks out the entire house. I decided to design and build an activated carbon filter for the skimmer's exhaust air.
The design is pretty straight forward. Two small containers to sit above the lid's exhaust holes and a frame and locator pins to keep them in place and prevent the carbon from spilling.
I designed in F360. The view below gives the general idea. Sorry too lazy to explode view of the components or animate.
Design was build for EASY 3D printing with no support.
1x piece base
2x hollow lower inserts, to be covered with nylon window screen.
2x hollow body towers
2x perforated lids. I may or may not add window screen to the inside of these.
The lids have little catches to prevent them from falling off. All of the components are permanently glued together except for the lids.
I made the cups fairly large so that I don't have to change carbon as often and so that there is good contact time. I don't know how long the carbon will last, time will tell.
The locator pins were set in oblong slots so that they could be adjusted before final glue up.
The lower inserts allow the window screen to be easily glued on and trimmed off, instead of printing the base and body tubes as a unified solid. I did not want to fiddle with trying to glue screen inside and wanted the screen elevated off of the skimmer lid.
See photos below for visual explanation.
Stage 2 will be dripping peroxide into the skimmer cup from one channel of my dosing system. I think a few ml a day will be more than enough.
Not much more to say. Pretty straight forward.
