I will also be shrinking the whole thing in the X and Y planes to 95% of its current size while keeping the height the same. This will allow it to print in one piece for the tube and lid.

Hi Max,
I really love the design — it looks great. I just wanted to ask how the chemical inlet and outlet system works. In the images, I’m not able to clearly distinguish how that part functions.
I’d really appreciate it if you could clarify.
Best regards,

The Main Differance is that I have added a spout for a black 6mm inner diameter latex tube to add and remove the chemicals. and shunk the hole thing in the X and Y to 95% of its original size. This allows it to just fit on a P1S or P1P print bed. I left the Z alone, so the film will still fit on the spools.

Recommended Print Profile for Morse G3 Style Development Tank (PETG)This print profile is designed for black PETG filament to ensure chemical resistance, durability, and optimal light-tightness for film processing. The settings are optimized for a balance of strength, material usage, and light-tightness. As this is a work-in-progress, these settings serve as a strong starting point and may be refined further.General Recommendations for all parts (using PETG):<ul><li>Material: Black PETG (Opaque black is highly recommended for light-tightness)</li><li>Printer Compatibility: Designed with print beds similar to a Bambu Lab P1S in mind, utilizing a split design for the tank and lid for easier printing. Ensure good bed adhesion for PETG (e.g., textured PEI sheet, glue stick on smooth PEI).</li><li>Nozzle Size: (User to specify, e.g., 0.4mm - assumed standard if not specified)</li><li>Layer Height: (User to specify, e.g., 0.2mm - can be suggested as a common default)</li><li>Print Speed: (User to specify or note &#34;moderate speeds typical for PETG&#34;)</li><li>Cooling: (User to specify or note &#34;use moderate part cooling as recommended for PETG to ensure good layer adhesion&#34;)</li></ul>Specific Part Settings:<ol><li>Tank Body &amp; Lid Sections:<ul><li>Infill Percentage: 75%</li><li>Infill Pattern: (User to specify if they have a preference, otherwise can be left open or suggest common ones like Grid, Gyroid, or Cubic)</li><li>Wall Layers/Perimeters: 5 (This is crucial for water-tightness and strength)</li><li>Supports: Likely needed for overhangs, depending on the specific orientation and design of the split sections. (User to advise or recommend &#34;as needed based on part orientation&#34;).</li></ul></li><li>Film Spools/Reels:<ul><li>Infill Percentage: 25%</li><li>Infill Pattern: Gyroid (This provides good strength in multiple directions with less material)</li><li>Wall Layers/Perimeters: (User to specify, e.g., 2-3 - can be suggested)</li><li>Supports: Likely needed, especially for the core and any intricate parts of the spool.</li></ul></li><li>Handles:<ul><li>Infill Percentage: 100% (For maximum strength and durability during agitation and handling)</li><li>Infill Pattern: (Not critical at 100%, but can be specified if desired)</li><li>Wall Layers/Perimeters: (User to specify, e.g., 3-4 - can be suggested for a solid feel)</li><li>Supports: May be needed depending on the handle design.</li></ul></li></ol>Post-Processing:<ul><li>Careful removal of support material.</li><li>Gluing of the split tank and lid sections is required. It is crucial to use an adhesive that is both suitable for PETG and offers good chemical resistance to photographic developers, stop baths, and fixers.<ul><li>Recommended Adhesives:<ul><li>Two-part epoxies: Many epoxies offer strong bonds with PETG and excellent chemical resistance once fully cured. Look for epoxies rated for plastics and check their chemical compatibility charts.</li><li>Specialized plastic welders/cements: Some solvent cements or specialized plastic bonding adhesives (e.g., those based on methyl methacrylate) can create very strong, chemically resistant bonds with PETG. Ensure compatibility with PETG.</li><li>Cyanoacrylate (Super Glue): While good for initial tacking, standard cyanoacrylate might not offer long-term chemical resistance for all photographic chemicals. If used, consider versions formulated for plastics and test thoroughly. Using an accelerator can help ensure a strong bond.</li></ul></li><li>Application: Ensure surfaces are clean and well-prepared before applying adhesive. Follow the manufacturer&#39;s instructions for cure times.</li><li>Testing: It is highly recommended to test a glued sample with your specific development chemicals to confirm resistance before processing valuable film.</li></ul></li></ul>Important Considerations:<ul><li>Light-Tightness: For the tank body and lid, achieving a completely light-tight print is paramount. Using black PETG filament is the first step. The 5 wall layers and 75% infill are also designed to help with this. After printing and assembly (including gluing), thorough testing for light leaks in a dark environment is recommended before processing valuable film.</li><li>Dimensional Accuracy: Calibrate your printer (e-steps, flow rate) for PETG to ensure parts fit together correctly, especially the spools within the tank.</li><li>Test Prints: It&#39;s always advisable to print a small section or test piece first, especially to dial in PETG settings and check for light-tightness and glue compatibility if you&#39;re unsure.</li></ul>This profile provides a solid foundation for printing your development tank. Good luck!
