Heyho

I wanted to mix a few samples with different colours or additives with epoxy resin and was looking for small mixing sticks. Unfortunately I haven't found anything really suitable in size.
So I constructed a mixing stick myself. It was so small that it could just be made cleanly with my 0.6 mm nozzle.

XS = 24,5 mm Diameter
S = 39 mm Diameter
M = 49 mm Diameter
L = 70 mm Diameter

Of course all models are support free for a good print!

Tip1: Mixing bowl. If you also want to print a mixing bowl, simply generate a cylinder in the slicer with a slightly larger diameter than the stirring rod and print it in vase mode.

Tip 2: Scale. You can scale the models up or down even further. However, make sure that the tolerances also become larger/smaller. That is why I have generated different versions as a starting point for you.

Assembling instructions:

Printable versions:
For the fully printable versions you only have to glue the axis with the mixer. If you stir epoxy resin with it, this bonding will occur and solidify over time anyway :P So a small dab of superglue is perfectly sufficient.

Also keep in mind that you can scale the axis to lengthen or shorten it!

Versions with a (wooden) stick:
For these mixers you need (wooden) sticks with different diameters and 3 mm wood screws to fix them (glue may also work). The advantage is that these are even stiffer & more stable than 3D printed axes. It is advisable to pre-drill the logs with a smaller diameter to avoid tearing the wood.

Wooden stick sizes:

XS = 6 mm Diameter
S = 8 mm Diameter
M = 8 mm Diameter
L = 10 mm Diameter

Have fun and keep printin!
