Wanhao Filament Reel Adapter

thingiverse

The filament holder on my Wanhao I3+ supports the reels from the same supplier, and these have a 52mm core. It will not cater for those with a 72mm core (i.e. every filament I have ever bought) The sides are longer than in the photos, bringing them flush with the bottom of the original bracket. It is *very* tight fitting. the early attempts were falling off, and that would be useless.
