If the costs are reasonable sure but if I can get a better deal for longer roll lengths why not? I will have to wait and see when the product actually launches.
Finally going to try to diy one myself.... I'd like some advice on motors if someone could help me out..

Or
DC 12V 15RPM 6mm Shaft High Torque Turbine Worm Geared Motor https://www.amazon.com/dp/B00EDMIH7E/ref=cm_sw_r_cp_apa_i_n3uECbP3J1MQ0
Also what power supply should I get? I know I need to convert from ac to DC 12v.
How did you attach your motor to the acrylic.
Also think it's possible to burn a Gear into pvc. Aka metal gear heat it up and put it into the pvc to make a pretty permanent bond?
Sorry for all the questions. Thanks in advance

I would probably not use either one of those motors- they would probably work fine for a while, but they are just not built to last. And the torque will probably be really low. And for the same price you can have a medium quality used motor.

Any power supply will work as long as it can supply enough amps- I always just use something off a piece of electronics I'm throwing away
You can attach the motor with nylon screws, or just a big gob of silicon and lay the motor into it (I did this). Anything that would exceed the holding strength of the silicon would destroy the housing anyway.
As far as melting metal into acrylic, it can be done, but I would recommend against it. This is better done in nylon or PVC plastic. Acrylic is fairly brittle, so the teeth of the gear would probably crack the acrylic when stressed. Acrylic is really a terrible plastic for most purposes, except for it's one redeeming quality- it's optical clarity.

It doesn't look like it is listed, but I would guess around an amp
I'm thinking about building one to fit in my sump. Space is very limited so nothing on the market fits.
But I do not want it to catch copepods and other living things so was wondering how to build a bypass for copepods. One way is to use a small 5mm LED and a clear tube to pull them in. But then you still need a way to allow a slow flow to let them through. Maybe combine that with a dripping system or dosing pump or another way that allows the copepods to pass through the filter? Might be some easy way to do it without additional hardware though.

Bumping this as i am preparing to build one as well. Any advice?
Thanks for the tip.
Allow me to say that's not correct. You can easily make it so copepods and other animals that are attracted to light go pass the filter while still filtering 99%+ of the water.. Heavy materials drop down but copepods swim towards lightsources. You can easily place a tiny tube of 1-2ml ID and trick copepods with light to go in it. Result is that they will be drawn to the light, get into that tube and get flushed. Another option might be to have x% of water that just bypasses the filter. This might allow some things to build up in your sump but the most part will still be filtered. Also keep into consideration that a too clean tank is always BAD. So having x% of the flow (even if its just 1%) bypass the rollermat is still a valid solution.
At the end, its even counter productive to filter out copepods using any filtermedia. Using light (just a 0.5W LED or something) can already be a solution.
I am fine with some pods being skimmed out its not like you could filter all of them out even if you wanted to.

my pods are doing fine.. i will say even with this filer ... i still have my filter socks in use.. they do need a changing every couple of weeks.. I also note that when you do a heavy stir of the gravel or clean of the glass ect.. make sure to check the unit.. mine is on a timer so it goes three times a day. but need to manual hit the apex unit that controls it when cleaning the tank... clogs up quick with a clean up..

A possibility might be a deburring tool... I use it when I drill holes in Acrylic. May not be small enough for a ¼ inch hole.
