Water Phaser

The design

This is a pump style water gun that is gear driven. It will shoot 100-150 ml of Water a distance of 4-5 meters. It features a magasine and you can get multiple shots out before needing to reload. It will give a good soaking and should provide loads of fun.

This is a 3d printed water gun that works on pressure. I kept the tolerances to a minimum but there will be some minor leaks but this will not affect function. Also, it is pump gear driven and does not use compressed air or an electric pump so don't expect Nerf like performance. 

I found that tilting the gun forward before firing helps when using the gun gets about half full of water. Also, the nozzle cap is used when filling the gun and will pop off on the 1st shot.  

Enjoy!

Assembly

It is easy to assemble and an assembly gif is provided as well as pictures (see below).

The tolerances are fairly tight. 

• The handle is fitted by means of a dovetail and may need some light tapping at first.  I used a screwdriver handle.  This is to ensure it does not slide off.  Some printers may give a tight fit others a loose fit.  Go slowly.
• The magasine top is fairly rigid at 1st and may need a screwdriver to wedge it open but thereafter if functions quite well.  There is back pressure when firing and you want the top lever to stay in place but it also needs to pivot for refilling the gun.  That is why it is a tight fit.
• I found that that wetting the parts helps then slide smoothly.  
• You can also use a very thin coat of vaseline where the magasine clips onto the phaser to remove any gap.   The design has no gaps but some 3d printers may leave some gaps.  Do do use vaseline on the sliding tubes as it blocks the white back pressure sealing parts.
• For the gear handle assembly look at the gif video or photos which illustrates how to position the parts when adding the gear handle.

If you have any issues please let me know and I will do my best to try to help.

I was informed that the gif may be a bit fast so I am including the assembly pictures in the text:

3d printing

Printing profiles are provided for the A1 min, P1 and X1.

ASA or PETG is best for this print since it holds water.  I have used and tested with PETG but have not tested with PLA.

My designs

I enjoy creating 3d models that others can use and appreciate. It is a very fun pastime. I find it very rewarding to see my models downloaded and printed. I put lots of thought, time and effort to create each model print out multiple iterations to make sure it works just right.

If you liked my model and wish to encourage me please give it a like or a boost. If you wish you can also help me with my filament costs. Thank you.
