Customizable filter step-up ring

SummaryThis is a customizable step-up ring I made using OpenSCAD, reusing some code from my customizable swirly bokeh filter. You can make any ring from 37mm to 90mm.Sometimes, the upper thread may be a bit thight. If that&#39;s the case for you, I suggest playing around with the end tolarance setting under the advanced tab.Also, if you want to use this ring for heavy filters, like I do, you should tweak the settings in the advanced tab to make the part stronger. I recommend using PETG to make the it more durable.Note: This script cannot make step-down rings.Print SettingsPrinter Brand: Bambu Lab Printer: A1 Mini Rafts: Doesn&#39;t Matter Supports: Yes Resolution: <0.14 Infill: 100%Filament: Any PETGBlack
