Best Nose Cones for a Der Red Max (BT-5,20,&50)?

[DabCat]

I'm looking to make some Der Red Max downscales with 13mm BT-5, 18mm BT-20, and 24mm BT-50. My trouble is finding the right nose cones. Which nose cones are the best fit? It looks like one of the nose cones in the BT-5 nose cone pack is a good match, but I'm not 100% certain. Same thing for the BT-20 pack, but I'm less sure about that one. And for the BT-50 pack, the 4" 2-piece nose cone looks to be perfect size, but the tip seems a little off. So which nose cones work best? And who sells them? Preferably all 3 because I would like to save on shipping. I also wouldn't mind using balsa, but I would prefer to use a plastic cone if one exists.

Also, if anyone could share a chart of all the nose cone codes/sizes/part #, I would love that too.

Sorry if this has already been asked, I tried a super quick search and didn't find anything. If there are other threads, I would love a link to them.

I'd probably just order a handful of cones from https://www.balsamachining.com/

If you are handy with Tinkercad or other 3D modeling tools, I recently posted a model of the DRM nose cone (BT-60) and shared the Tinkercad for it. You can use that as a starting point for making smaller versions. When you scale it down be sure to adjust the wall thickness so it doesn't get too think and shoulder diameter so that doesn't become too small too.

Estes Der Red Max nosecone (PNC-60AH) by Arogen67

I wasn't satisfied with the accuracy of some other models of this nosecone so I set out to make one of my own. I compared and measured a lot from my Der Red Max rocket to make this one as close to perfect as possible, and I expect any deviations are far too small to be seen by the naked eye...

I know this is being picky, but from my measurements the height of the BT-60 DRM cone (not including shoulder) is 6.72 inches, not 6.62. The other sizes are scaled off of that.

I believe the BNC60AH is the balsa version of the BT-60 sized Der Red Max.
