An idea from Neoney, with help from TheFallen and Klaus for fluid dynamics. 🤘
While thinking about a way to lower VOCs for non-outside vented printers, came the idea of an internal recycler.
As auxiliary fan is 99% useless, there was a few space to use for this closed loop filter.
Objectives:
- bolt on stock mounts
- use aux fan header with a y splitter with no require change in config files
- easy carbon pellets change
- easy components find
The design is an open box with a pair of 5015 wide mouth blowers pushing air through a pair of independant easily removable cartridges.
I tried to use the minimal fixatures , so you'll need only 4 M3x25 for fans+covers and both stock screws for panel mounting.
