3D Printing the modified parts

No supports or anything similar needed.
In order for bridging helpers to work correctly, you need to print a layer height of 0.15mm or lower and 3 outer perimeters or more.
At that point, infill won't matter and can be pretty low.
After printing, remove the two tiny bridges at the end of the module holding up the "lip".

No supports or anything similar needed.
In order for bridging helpers to work correctly, you need to print a layer height of 0.2mm or lower.
2-3 perimeters should be enough.
Infill doesn't matter.

You will need flexible filament for this (duh). For example, this was tested with Fiberlogy Fiberflex 40D.

There are many guides online on how to print multi material if your printer has only one nozzle and you can look for more detailed instructions for your slicer/printer. However, here's a brief summary:
- Tell your slicer that your printer has two hot ends (even if it doesn't).
- Import the two STLs into your slicer, make sure it detects it as two parts of the same object for multi material printing.
- Set the filaments correctly for the flexible and rigid part.
- Make sure your printer supports M600 or a similar print pause/filament change G-Code command.
- Set M600 (or whatever command your printer understands) as the custom Filament Change/Tool Change G-Code. In PrusaSlicer/SuperSlicer, you find this in the Custom G-Code section of your Printer profile. In Cure, there is an Extension called Post Processing that you can use to add a custom G-Code script.
Set the layer height to 0.25mm for the bottom 1mm or the entire print. You can set it lower, but then you'll have to change the filament more often.
If you have done it correctly, there should only be 4 manual filament changes for the entire print.
No supports needed, infill doesn't matter, 2-3 perimeters recommended.
Good luck!
