Seestar Spiker
If you like spikes as seen in astrophotos done with Newton telescopes you will like this. I used TPU shore 95A!
If you like to print it with other material you need to modify the diameter with Fusion 360 or you have to downsize it in your slicer to a value <100% until it will fit.
However also if you use TPU you maybe have to adjust the diameter for good fit.
V2-Version has smaller bridges.
