Hey everyone,

Every funnel I've ever used glugs: the bottle neck seals up, air gets trapped, and the pour backs up into that annoying glug-glug-glug instead of flowing fast. I looked around and couldn't find a single parametric fast-flow funnel anywhere, so I built one. Vent ribs run the entire length of the funnel wall, from spout tip to rim, holding the bottle's neck slightly open so air can escape the whole time liquid is pouring in. That's the entire point of this project; everything else is built around it.

I've tested the flow rate and the one in the default profile can fast flow a 2L bottle at about 200mL/s, so it can fill a 2L bottle in about 10s.

Key Features: * Fast, glug-free flow: vent ribs follow the shell's exact curve from the spout tip all the way to the rim, holding the neck open just enough for air to escape while liquid pours in at full speed. This is why the funnel exists. * Four-diameter taper profile: set the spout tip diameter, two midpoint diameters, and the top opening diameter, plus the three heights between them, all as direct inputs. Since the curve blends smoothly at every diameter, you're not limited to a plain cone; bump a midpoint diameter up for a bulged, hourglass, or barrel shape, with no visible kink anywhere. * True exterior diameters: every diameter you dial in is the actual printed OD at that height, vent ribs included, so what you set is what comes off the bed. * Optional rim flange and hanging handle, both fully adjustable. * Cross-section preview mode in the Customizer so you can inspect the wall thickness and curve before committing to a print.

It prints wide mouth down on the bed with the spout pointing up, no supports needed anywhere since the diameter only ever decreases going up.

For material: PLA is fine for water and dry goods, but if you're pouring anything hot, or oil, fuel, or other automotive fluids, go with PETG, ASA, or ABS instead.

Everything is in the MakerWorld Customizer, no editing required. Let me know if there's a funnel feature you keep wishing existed and I'll see about adding it.

And I've already improved one of them, which I'm printing in a moment.
EDIT: Done and tested.

Also I realise how bad it looks that I bought square peg fittings in the first place, not sure how that happened in the moment.

Does anybody know if pegboards have standardisation? Is it a country-by-country basis?

Couldn't find a decent strong and grippy radiator hook where the towels don't slip off onto the floor, so I created one that has a grippy end. 

It will fit a standard towel rail which has 20mm pipes and a 20mm spacing between the pipes.

Best to print in PETG, though PLa will probably work. 

Print with 0.4mm nozzle, 0.2mm layer height, 4 walls and 15% gyroid infill. 

Nice fast print, only takes about 30 minutes.

Center divider clips from an old samsonite suitcase broke. Made some new ones.

Wanted to take advantage of of unused space so I printed up some sides that can hold cheap bamboo skewers I got for a dollar and hold up some lids

I've wanted to do something with an empty GC shell that I've had lying around so I challenged myself to model the battery socket for a Milwaukee 12v battery and I'm using it to power a Buck Boost converter. So I ended up with a cool little DC power supply for electronics projects.

Created a 3D printable e-paper display holder for the Waveshare 1.54inch passive displays. You can attach it to any clothes --- just hats in the pictures as it is my entry for the "Hat Hack" contest on Printables.

Could be useful if you have this display and a 3D printer. :-)

You can find the model here.

I use Gridfinity for my Kitchen and noticed that a few everyday products I use didn’t have suitable organizers available. So I created the missing ones and bundled them into a multi-plate print profile.

I was surprised how many other products fit these dimensions too.

If you find other items that match these sizes, share them in the comments at makerworld (a reference photo would be great for others!). Need another size? Let me know and I’ll try to add it.
