Bacteria model

Rod‑shaped bacteria model designed for demos and displays.The kit shows the envelope layers and key internal components, and uses real 1.75 mm filament to create realistic pili and a helical flagellum. What’s included: Capsule shell with perimeter anchor holesCell wall ring (blue)Plasma membrane ring (green)Cytoplasm plate (yellow)Nucleoid / chromosomal DNA (rope‑like solid)Plasmid loops (small DNA rings)RibosomesmRNA strand, polymerase bead, protein beadsPrintingPETG or PLA · 0.20 mm layers · 3 perimeters · 15–25 % infillNo supports requiredAnchor holes sized for Ø 1.85 mm (tuned for 1.75 mm filament; lightly ream if your printer runs tight)Assembly (cyanoacrylate/CA glue)Dry‑fit, then glue the cell wall and membrane rings onto the capsule.Glue in the cytoplasm plate.Place the nucleoid centrally and the plasmids away from the wall for visibility.Glue ribosomes scattered through the cytoplasm (slightly fewer directly above the DNA).Optional polysome: glue the mRNA starting near a plasm
