Fleece Filter V2.1

Here is the spun text: You'll need a VliesFilter for your Tech Pool with its own chamber for water intake, just like it's normally used for filter socks. You'll need a 190x76mm cutout. I couldn't get this done myself, so I made an adapter with the correct size and printed it out. This one isn't included because every tech pool is different. The VliesWatte measures 157mm in width. I bought cheap ones on eBay for $40 per square meter and 50 meters long. Use M4x12 nylon screws! For the inner filter, you'll need about 1m of Acrylrohr in 7x5mm (see I1). The filter has been running at my place for three months now, with two months using a breadboard setup for motor control and one month with a completed version on an SMD board (see picture). Check out the dirt on the right-hand roll - it's working flawlessly and giving me crystal-clear water. The sedimentation system is also doing less work and needs to be cleaned less often. I highly recommend this kind of thing to everyone. Warning! You can order the motor control board (unpopulated, populated, or complete with housing, motor, and switch) here: https://www.ebay.de/itm/183879964217. As written on that page, please choose the unpopulated version and solder the components yourself. You should already have some SMD components soldered or know someone who can do it for you. The firmware features are described there. However, you could also build your own motor control board or simply turn the roll by hand without a motor. You can also make your own holder and use an overflow tube or intake hose. The two rolls with the filter material should be above the water level (see above). If not, the dirty roll will actually get washed with the clean water... At my place, they're now hanging on top of the baseboard. I had to slow down the new roll a bit (see plastic step with some screws as a weight), because the water would otherwise carry away the VliesWatte too quickly and not effectively push it against the filter wall. I'm using a version with a ball bearing, which was twice as bad - I had to slow it down first and secondly, my ball bearings also rusted. So, I developed a new version without ball bearings. You might need to make sure the motor doesn't pull out the entire inner filter when spinning it further. I've fixed the inner filter for safety reasons. I printed parts with 10-30% infill in PETG without support. Depending on interest, I might create a video about this, we'll see... Some parts need to be printed multiple times: 2 x G1, 2 x I1, 3 x I2, 2 x O1. 2 x O2, 3 x R1, 2 x R4, all others just once.
