Lotion transfer tube

Have you ever get tired of not being able to use the lotion or gel at the bottom of the bottle because the tube isn't long enough?  Tired of making a mess and spending a lot of time to move the lotion from one bottle to another?  This device will help to solve those problems.  I printed it in TPU, but other rubbery filaments should work too.  No supports needed.  I used 1mm perimeters (top, bottom, sides).  It requires the cap from two of the bottles with the pump assembly removed.  You can remove the assembly by cutting through the bottom part of the assembly.  I used a Dremel tool to do that, but other methods should work too.  Be careful not to damage the cap.  Slide the caps in on each side so the the tops are butted against each other.  The caps need to be a tight fit going in so they won't easily come back out.  Please see pictures for more information. 

After the transfer tube is assembled, screw one bottle into each end.  You might need to squeeze the transfer tube to keep the cap from spinning.  Then you can stand the bottles on top of each other, as the pictures show, and let gravity do the work of moving the lotion from one bottle to another.  It's also possible to swing the two bottles so that centripetal force moves the lotion to the new bottle.  Be careful when swinging the bottles.  Squeezing the bottles can also work.
