Customizable Bag Clip - PLA Compatible by SpoonUnit

Last crawled date: 3 years ago

This remix takes an existing design and moulds it into something completely customizable.
I started by looking for the best design I could find for bag clips. I settled on MasterFX's verified and highly collected design. As usual, the complex design of a good model is, at first site, a challenge for a customizer as the entire object must be built from primitives instead of a set of extruded sketches followed by the use of easy filleting tools. Also, to get a great customizer, care needs to be taken to ensure a good preview appears when differencing objects.
About three prints were required to weed out issues with the model. The primary issues were the need for some good support around the "back" of the hinge. I've not seen a slicer yet than can infer that the best support would be an arc. This immediately led to an understanding that, as usual, the layer printing height chosen by the printer should ideally be taken into account in the design; I would expect the best results where meshHeight is a multiple of the layer height, which you should also enter to create one layer of separation between the model and the support. As this is intended to be an item doing regular duty, and not an objet d'art, I've set the delivered variables to match a 0.3 layer.
The customizer variables do their best to explain the purpose of the variables, but you'll probably find that experimentation is best. There are no constraints to ensure the model is sensible, so do look carefully at the result both in the previewer and in your slicer.
One thing which is not controllable is the indentation and matching raised part. Rather than create yet more variables, this aspect is a function of both the clip height and the clip thickness. Use your own experience and look in your slicer to ensure you haven't created something unprintable. If you print with two shells and a 0.4mm nozzle, you should be able to comfortably handle vertical angles of 60 degrees.
Clip lengths at 60mm, 90mm, 120mm, and 150mm are added to the thing as examples. These all use a clip thickness of 16mm and a clip height of 9mm with a mesh height of 3 and the hinger outer thickness of 3. They should all prove to be very sturdy.
Finally I'd really appreciate any feedback, and I'd love to see any crazy large (or crazy small) prints, or in fact, any prints at all.
Enjoy.
