Replacement clip for the cover that sits over (or under I guess, as mounted) the grease filter on Ikea Luftig and other Whirpool made fan hoods. It's the big sheet metal cover you see if you look straight up from the stove. A local supplier wanted ~€40 for a set of two, so I spent and afternoon designing a replacement out of pure spite. 

The clip holds on to the 5mm ball shaped end of the pin.

The original clip has very stiff spring but the rest is made of very thin plastic. This means it requires quite a bit of force to operate while at the same time being quite fragile, and hence easy to break. This replacement needs less force. I found this clip nicer to operate so I replaced both my clips even thou only of the original was broken.

I printed this out of petg but I'm unsure if that will hold up. Petg might do with my induction stove but probably not with a gas stove. The clip will probably not hold up forever (the plastic will deform around the pin reducing retention force), so perhaps print an extra set when you are happy with the fit as it's less than 10g of filament for a pair. I will add more information on longevity (and petg) when mine fails.

Print flat on the flange face with no supports.

Pin location tolerance

The slot (like on the original) provides a few mm of tolerance in the slot direction. My clip is also designed so the whole clip can slide +-1 mm perpendicular to the slot. This way the pin can be out 1 mm in any direction and still fit. 

Retaining Tab

The retaining tab is a thin 'spring'. The lip is an unsupported overhang. Don't use support here, just let it droop a little and fettle it with a knife after printing (image 4). To remove the clip from the sheet metal press into the slot that is visible on the short side hard with a flat screwdriver (image 5). This will break the tab on the layer line and free the clip. The clip is destroyed by this.

Parametic Model

It's likely that you need to adjust the model after your exact use case (pin, cover etc) and printer. I have provided a parametric FreeCad model. Look for the variable block called 'dim'. Note that if you increase the depth that the pin is held (pin_depth) over 5mm you also need to increase the depth of the clip body (clip_depth). If the pin is rattly, decrease pin_size. If the pin is to easy to pull back out, increase pin_squeze.

There is also a step model.

I think the whirlpool part number is C00938301.
