Description
Either print Black and Silver with dual extrusion (printing with 2 plastics) or print the Full version. You can, but it is very hard to, print this design in 2 colours seperately and later assemble them. I have seen someone do it.
Supports are needed to print this correctly. The design has a lose cap as we experienced it was easier this way to remove the supports. The hole for the USB is 13mm by 5mm by 31mm. The deeper file contains a depth of 47mm. This might differ a little between the normal and TI version.
We printed the model with 0.4 cores at a layer height of 0.06mm or 0.1mm, with PLA plastic. Infill can be 10% or more. Sometimes supports can appear under the fan, if this happens adjust supports to touching builtplate only.
We use kingston datatraveller USB sticks, any other USB stick should be possible if it has the right dimensions. Link: https://www.amazon.com/Kingston-Digital-DataTraveler-DTSE9H-16GBZET/dp/B00DYQYITG
The higher capacity 64 and 128gb kingston version also fits.
After printing: remove the brim and supports. Sand the sides for a better finish. We like to use steel wool for polishing (just make sure this doesn't get into the USB hardware). Superglue to glue the USB stick in place and then put the seperately printed cap on. Before glueing make sure the cap fits snuggly.
The files were made in blender, so we also included the project files if you want to tinker around with it yourself. It includes the final file and the file without booleans applied, this way it is easier to make the hole bigger for example. Just make sure to apply the booleans and delete the not needed (boolean) meshes before exporting to .stl
