Printing advice
I suggest adding a support blocker in the region where the spring is inserted (Image attached)
Story
I designed this part because I had a Kärcher vacuum which had the hook broken off of this latch button. Because this latch holds the dust bucket, the vacuum can no longer be used. I recreated it from the broken part and the printed version works for me but it could be improved.
Especially because when you pick up the vacuum by its handle, the weight is hanging in part on this printed hook, therefore the strength could be improved.
V2: Now the model is split in an upper and lower part. Therefore you no longer need to almost break the legs of the clip to force it in place.
FYI: Kärcher has a spare parts store, where you can get individual parts. Love to see it!
The author marked this model as their own original creation.
