This is a series of mixing cups with a spout shape so that you can pour accurately without product dripping down the sides. The spout is not too big so it doesn't interfere with complete stirring. I made them for use with 2-part resins, epoxies, and silicones.
Provided sizes range from 1 - 12 fl. oz. / 30 - 360 mL. There is just one shape, just scaled to various volumes. Other sizes or shapes could be created if there is demand.
The size is labeled on the bottom.
Print settings:
- Layer height: Up to you! 0.3mm works fine.
- Material: PLA, others should work but untested.*
- Supports: None
- Vase mode: should work, but it is optional and untested.
- Arachne: enabled; particularly if you are on an 0.4mm nozzle — the walls are 0.6mm.
* May need to tweak XY compensation to thicken the walls if they are too flexible or too weak in PETG or ABS, etc.
Random notes:
- Volumes are approximate. They absolute maximum liquid the cups can hold is just slightly higher than the labeled volume. If you are using them to hold or mix fluids, you probably want to use a size or two higher than the actual amount of fluid you want to hold.
- Single wall prints can exhibit tiny pinhole leaks that make them not truly fluid tight. These cups are designed to use little filament since they may be only used for a few minutes at most, and I haven't seen issues that prevent them from being effective for this use. However, I would not count on them holding fluid perfectly indefinitely as-is. You could increase the wall thickness with XY compensation if it is an issue for you, or put tape around them, or have clay on hand, etc.
- Epoxies and resins can create significant heat when mixed, especially in large volumes. Please be aware of this when using mixing cups made of thermoplastic. :)
- If you use a bed adhesive or print release agent, and you want to nest these cups, you might want to make sure that it doesn't interfere with curing of whatever you mix. The cups' outside bottom doesn't contact the containing cups' inside bottom when stacked due to the spout, but better safe than sorry. I will update the model if I learn of any notable inhibition issues.
- These cups are NOT marked with volume gradation scales. I use a gram scale so I have not needed this.
