Aquarium Pump Adapter for Step2 Water Table

prusaprinters

<p>This is a set of 4 parts to adapt a SpacePlaces DP430 aquarium pump (I found it on Amazon) to a Step2 water activity table. The tubing is TotalPond ½" vinyl tubing.</p><p>The 4 pieces are:</p><ol><li>An inlet adapter. I printed in PETG. PLA would probably work. It screws onto the existing drain piece, so you don't need to modify anything there. It fit the drain and the pump inlet pretty snug and didn't leak much, but I did put silicone around the edges of both joints.</li><li>A holder for the tubing. Also PETG/PLA. Holds the top of the hose down to point the water into the upper basin.</li><li>A replacement grommet/seal for the drain. The stock one has the stopper attached, so I printed a TPU one that is essentially just a washer. Could be replaced by any piece of rubber, so it doesn't need to be printed.</li><li>A replacement drain plug. It's sized so you could just use the stock one if you want to or don't want to print TPU. This was TPU.</li></ol><p>I drilled a hole up through the bigger support column. It's hollow, just try and miss the screw in the middle right at the base. The pump mount is just zip tied to the bottom by drilling through the outer layer of the lower basin.</p>
