Not really a remix... I have reduced it to 75% size and added alignment pin holes and a center hole for a 1/4" wood dowel.

From the original Thing - Wind Turbine: https://www.thingiverse.com/thing:3095317

I made these three years ago and they have broken several times due to UV light, storms (high wind) and rough handling.

These will spin in a very light wind and I discovered accidentally that birds do not like them.
I have them hanging from a handrail to keep birds from perching and crapping on the handrail.

The spinner tips are weak and I have now added a file for tip reinforcement. This is shown in the video listed below.

It is quite difficult to align the two halves for gluing so I have added holes for 3mm bamboo alignment pins.

They have frequently broken at the joint seam so I have added a center hole for a 1/4" dowel which will hopefully help reinforce the joint.

Holes were added to the original stl file using negative volumes in PrusaSlicer.

Tips are gladly accepted and much appreciated.

Please Note:
If you load the file: visVent_75_Size_With_Center_And_Alignment_Holes.3mf
into your slicer, you will not see the holes.
BUT... go ahead and slice it and you will see (in preview or layered view) that the holes are actually there.
They just cannot be seen from the .3mf file for some reason.
The .3mf file was created in PrusaSlicer and the holes were added as negative volume cylinders.
The file works perfectly for me.
