Holder for PT Level

I have a cistern and use a PT Level to monitor it (www.ptlevel.com) and wanted a decent way to hold it (other than 2 sticks haphazardly stuck in the ground) . The cap is 170mm across.

I have uploaded version 3 as version 2 the bars finally broke off. I made it a little shorter and added some support to the bars so they are not flimsy anymore.I also changed the following:
increase fill to 50%
Wall thickness was 1.6
speed was 60
Had Feline printing supervision (see photos)
