There's definitely a number of funnels on the
GH Accessories page from Delta 3D -
flexible general multi-fit, GH only (
normal and
mini size), 2in1 GH+doobtube (
normal and
mini)
(there's also the MFLB Finishing grinder funnel which could be printed to fit the GH upon request, and really the customisation is endless depending on what you want to do)
yeah yeah, I'm pedantic, but consider this a plug.
1 vape, many options that are reasonably self explanatory, but the differences could be best explained by someone who has handled multiple versions, which I suspect was what
@david8613 was after.
I'd probably go for the flexible or the mini, for durability/pocket-ability. If I used a doob tube, then the 2in1 makes sense. The V1 full size options seem to be the lesser choice - I think
@Ratchett made the mini after comments from people using the full size version which pre-dates the other options AFAIK. Seems the OD is about the same on the flare end between the sizes, and the GH end is shorter and stronger. The full size is needlessly big, that volume looks like it could handle many chambers worth of ground herb.
I'm sure
@david8613 was just after some user confirmation that the item is good, to which of course it is, it's a Delta 3D accessory. You can't really go wrong, but I don't know, I've never tried.
I will note, the plain undyed PLA is the better choice for this task
But do note that printed PLA has a massive surface area and will become caked in kief, harvest bacteria and is a pain to clean.
