tub
- issues
- aligning grooves only working for single tub. craps out with multiple cells.
- side eyelets mess up on one side when trying to move in and out
- might make internal corners rounded just to look nice
- first print had laminated cracks
- located where grooves meet at corners
- might shift grooves down a few milimeters relative to the previous side
- might make interal corners of tub rounded using a Minkowski sum
