Holds V5 & V6 accessories (maybe others, those are the only ones we have). Those versions clearly require a completely different holder than V7 and later. The older version has the spring in the holder rather than on the accessory.

The spring action of the clip isn't quite as strong as I'd like but it does hold even the heaviest of our accessories. Maybe I'll repost with a thicker clip to provide more holding power.

I printed mine in draft mode and ended up needing to do a little filing of the clip slots before the clip would slide into them but afterwards worked just fine. If you use a higher resolution than I did you probably won't have this trouble.

Update 14/3/21: I posted new STLs because some slicers were reporting errors on main part. While I was at it I thickened the clip so the spring action would be a bit stronger. Both parts have now gone thru a Netfab repair cycle so slicing should be smoother.
