Fluval Spec V water diffuser and skimmer

I recently got a Fluval Spec V aquarium for my daughter's betta. Doing some research it turns out they don't like too much water flow. There is a part by fluval that gave me the inspiration for this make. The diffuser should be printed with the flat side down.
I'm not an expert but it seems to work fine.

The other flat part, the skimmer, is to be inserted in the grill and placed just below the waterline. By forcing the top water through the filtration system it helps remove any surface build up. I got the idea from an online DIY video where a plastic card was jammed between the filter sponge and the grate. This seems to work just as well and is a quick print.

I added a V2 which has a riser to also push some flow at the surface. It seems to help in removing surface debris. It can be printed flat but requires support for the riser (make sure no supports are printed by the holes).

The cap and nozzle are for V2 to block the upper flow or to increase the velocity of the waterflow
