This print is for securing large waterbottles, such as hydroflask or nalgene, in standard car cupholders. Since larger waterbottles are heavier, this print has an expanding base to secure the adapter.
Some assembly required:
Place the circular fastener in the bottom of the lower piece, with the diagonal facing upwards.
Next place the 4 rectangular plates in the remaining slits of the bottom piece, with the diagonals facing downwards.
Place the upper piece on top of the lower piece. Rotate the upper piece until it falls into place.
Place the assembled adapter into the desired cupholder.
Finally, tighten the screw into the fastener through the upper piece. This will lock the top and bottom pieces together, and extend the plates into the cupholder.
Recommended Settings: Increase the infill of the screw to 80% or higher or it could break with mishandling. All other parts will be fine with standard infill.
See pictures for assembly examples. In these pictures, the upper piece was left unfinished to show assembly steps.
