prusaprinters

Update 30/07/22;I have Uploaded V3.4, This generates a Single Custom Bellows without throwing any errors.V3.4 also includes an automatic two stage bellows generator. You can now print the bellows in two parts allowing for longer bellows than a single one would allow on the build height of your printer.Now the model is generated with 0.8 mm Thick walls. You can print in Vase mode with a 0.8 mm Nozzle, 0.6mm, 0.5 mm or even 0.4 mm if needed OR print Normally with a 0.4 mm Nozzle extruding two perimeters with the Model having 0.6 mm thickness to allow for extrusion Overlap of 25%.All the Sketches / Planes  etc.. are clearly labeled for you to see how it's made. Here is a perfect example of an end use case, I have added The Multi Part Version to Kaishou's Vega 4x5 View Camera Find it here on Printables!I have Performed a light lest by printing the Light test model in Black TPU and 0.8 mm, it has the same thickness as the Bellows. I can Confirm no light leak in the test model (at least to the eye), have a try for yourself.I have also test printed all the connections with the test print models and they have a good tight fit.If your Bellows are too Stiff (Depends on the hardness of the TPU you have) at 0.8 mm thickness, try printing the Light test model in Vase mode (0.8 mm Nozzle, 0.6mm, 0.5 mm or even 0.4 mm if needed) with Black TPU. From my testing all model tolerances should allow it as the 0.8 mm version is nice and tight.I printed mine with a TPU Shore hardness of 95aPrints in Vase Mode with the big side on the bed and a 0.1 mm layer height when using a 0.4 mm Nozzle and 0.4 mm layer width. Scale up the settings from there for bigger nozzle sizes. I also recommend printing with a brim(outer and inner).This Printable really benefits from the PrusaSlicer 2.5  release, due to the vast improvements in generating perimeters.
