thingiverse
Fussy crustaceans infesting my underwater habitat require prompt eviction still a work in progress though I'm just figuring out SketchUp this is my initial illustration so proceed at your own peril Edit I tweaked the bar dimensions correcting them to 4mm with 9mm spacing and refined the lid design also added structural reinforcement near the entrance to prevent sag printing resumes and I'll continue updating as needed
