Summary

This is a four piece towel bar with dovetail joints and two adapter caps that can be adjusted to fit almost any towel bar setup.

This specific setup is for a shower towel bar (45cm + (2)1cm caps). This has been printed and tested without issue but is open to improvements :)

Instructions

All pieces were printed with rafts on a Replicator.

1) Print towel bar_part1.stl, 2, 3, and 4. Parts 2 and 3 need exterior support for the female part of the dovetail joints. Minimize sanding beyond obvious cleanup because you want the joints to be as tight as possible.
2) Modify end caps if needed. Otherwise, print two of rod adapter_v1.stl

Printer specs:
I printed all parts with .15 layer height and 15% infill with 2 shells for strength. These can be modified as you please but I would def recommend no less than 2 shells for all pieces.
Build platform: 118C
Nozzle: 230C

Print time:
Towel bar (per section): 2hrs 10mins
Adapters (per end cap): ~19 mins
