Ebb and Flood / Flow pump adapter

prusaprinters

<p>Simple ebb and flow adapter for Ikea Trofast storage box. Inspired by Chillichump's implementation of Ebb and Flood/Flow system. Optimized for easy printing. With this design you can attach the lid right to the bottom of container.</p> <p>A few tips on assembly. You can get away with a rough cut hole, if you don't have a large enough drill bit. I used a simple utility knife which produced a round-enough hole. Also I drilled 4 small holes on the bottom corners of the container, so that the holes are taking care of the last bits of standing water that collects in the corners. This does not materially slow down the fill process, which took 33 seconds with expanded clay and 12v pump.</p> <p>The 11mm outer diameter hose - just slide it into the bottom of the screw (not the head). This is how you connect the pump. Also i used a bit of adhesive to glue in the mesh-tube for water inflow. For the overflow, you can friction-fit and adjust the height to your liking, and then set with adhesive.</p> <p>What i could have done better? - I would have devised a mesh on top of the overflow tube, as testing showed that small expanded clay pebbles can get into the tube. So far i just placed an extra mesh on top of the tube. Maybe in v2...<br/> Also my design leaves about 6mm of standing water, due to the height of head bolt. Thus a few drainage holes in corners of container are required.</p> <p>Printed in Hatchbox wood PLA. 2mm brim for the standing tubes. Rest of the parts are easy, require no supports. Print bolt in on-the-head orientation.</p> Category: Outdoor &amp; Garden
