Garden Hose Washer - EASY TPU

An easy “my first TPU” print for those starting out - and very useful.  Presenting a simple garden hose end washer - complete with little tabs to prevent it from falling out once installed in your hose nozzle or sprinkler head.

Update: Added single item STL file version of this model on July 17 2022

How to print:

.3mm draft mode, any FLEX or TPU profile you like.  Use either FLEX or TPU filament.  Shore 95 to 98 gives a serviceable washer, although quite hard (tighten mightily).  Shore 80 to 85 (Ninjaflex) gives you a beautiful washer that is quite pliable.

As sliced here uses Concentric top fill and bottom fill patterns - better leak prevention than a cross hatch.

If you have never printed TPU or Flex before, be sure to use something like glue stick or elmers glue on the bed to allow a good release and not damage your PEI surface.  If using a prusa MK3S/+ printer, back out the tension on the extruder gears to the last two threads.
