So, stumbled across this use-case this morning when trying to get a particular spindle to fit on the V-Spooler default drive shaft (for the spool to wind to). I'd created a universal spindle system for the AMS Lite AMS Lite Universal Spindle by Jeff Smith - MakerWorld because I was tired of always having to have this adapter or that, and this makes using any type of spool on the AMS Lite easy. 

Well, needed to re-spool from a cardboard spool that doesn't work correctly in the AMS and didn't have any of the 27 different adapters that are out there so I just grabbed one of the tapers from the AMS Lite Universal spindle and darned if it didn't fit the V-Spooler default shaft perfectly (at least the one I printed when the V-Spooler came out, might be different now? Don't know).

So, give this a try, it's an easy and fast print, and if it works for you, leave me a positive review, if it doesn't, let me know what doesn't work and I can likely modify it so that it will. I'm always looking to increase the versatility of my models, and while this one is something I stumbled across and hasn't been tested 20 ways from Sunday like the Universal for the AMS Lite was, it worked great for me this morning.

Note, I still use the axle/spool carrier for the receiving spool from the original V-Spooler, I think there is a newer one that is bigger.  The original was smaller in the middle.  You can get the older “universal spool clamp” as one of the downloads on the v-spooler model, or you can just upscale the taper in my model by 5% and it will likely fit.
