Drill Powered Water Pump V1.2!

This is a compact, 3D-printed centrifugal water pump designed to be powered by a standard electric drill. The pump features a simple snap-fit housing with an internal impeller and a splash guard to reduce water spray during operation! Connected via a 9mm shaft, the design can output up to ~0.5 liters per second when submerged in water, making it ideal for small-scale water transfer, experiments, or demonstration purposes. Easy to print and assemble, it’s a great example of functional 3D-printed engineering. This pumps should take no more than 55 grams of PETG filament(0.12lb),(1.94OZ).

Features:

• Better sealing cap to prevent leaks/better alignment for screw holes
• Smaller and taller entrance to make it more efficient
• Slightly bigger/More efficient turbine allowing it to run even with air mixed in with water(Ex; If running low on water, it will continue to pump water well
• Longer shaft with a new splash guard to let less water get onto the drill
• Very easy to print
• Output pipe is 26mm wide(20mm inner diameter)
• Output pipe is 1.02" wide(0.79" inner diameter)
• No grease or lubrication is necessary(Unless you want, this might make the turbine itself seal better), the water/liquid keeps all the parts cool and prevents too much wear
• It is able to pump 0.5 liters per second as shown, although this was done on smaller scale and over a short period of time, id like to hear what results you guys get!
• Now a longer axle!

How it works: 

• When tightening onto a drill of sorts, make sure to put the shaft all the way in to prevent the turbine from being unbalanced
• Dunk fully in water to make it work better and make it more efficient
• Hold the housing to make it more stable, it can run at full drill speed(The faster, the better)
• You can either use it like shown with a gif, or stretch a pipe over the output using a hose clamp to hold everything together

Tips:

• I highly recommend printing with at least PETG, though PLA+ is probably acceptable
• AT LEAST 1mm thick walls, and 30% infill(you can scale up from there as much as you like). Support structure is necessary for all parts, adhesion is optional. 
• I highly recommend that you print the axle separately and make it have more infill/walls
• Right after assembling, you can spin it up with the drill to loosen/sand everything, just make sure not to run it dry for too long or you could risk potentially damaging it.
• You can play around with the size of the turbine based on how your printer handles tight tolerances
• I didn't use screws, but there are screw holes if needed(depending on your screws/bolts, heat them up like with a lighter to make sure the plastic doesn't crack when inserting) 

How to assemble:

• Take the housing (same way it was facing when it was on the buildplate), and put in the turbine itself(also same way it was facing when it was on the buildplate)
• Then take the shaft, insert it through the bottom aligning it with the turbines key like shape(I used a hammer to lightly tap it in while the configuration was sitting upside down)
• Then Flip it again(up side facing up), and put on the lid/cap (same way it was facing when it was on the buildplate), and use screws if necessary(I didn't need them because my printers tolerances aren't very good so it just snapped in place and held well even during operation 

Thank you all for downloading, boosting, liking, etc. I would love to hear how it works out for you guys, what results you get, what you think, any problems/questions.
