Float Switch Bracket

thingiverse

This is a bracket to hold float switches on a rimless aquarium. It works great in other situations where the container doesn't have a large lip. The mount is adjustable so you can set the desired switch position exactly right. To avoid rust, I recommend using nylon hardware for the nut and screw. I've included OpenSCAD files that let you adjust the following features: Bracket: - length - the longer the bracket the more range available (default 60) - width - sets the width of the bracket (default 25) - switchRadius - how big the hole is for the switch (default 5) - switchArmLength - how far out the switch can be held (default 30) Mount: - width - width of the mount (default 25) - baseLength - how far the back of the mount extends down the back of the tank (default 50) - glassThickness - thickness of the glass (default 6) - clipLength - how far the inside of the clip extends down into the tank (I try to keep this out of water) (default 20) - screwDiameter - size of the screw hole (default 3) Here's a link to the openSCAD code on github if you want to suggest a revision https://github.com/mjrsnyder/FloatSwitchBracket. Enjoy! Print Settings: Printer Brand: RepRap Printer: Prusa i3 Rafts: No Supports: No Resolution: 0.2 Infill: 15% Notes: I'd recommend ABS because PLA supposedly degrades over time. I've been using PLA in a freshwater tank for 6 months and have had no issues so far. I do avoid getting the bracket wet though. Post-Printing Here it is assembled. Later, I changed out the metal hardware with nylon to avoid rust. Here it is installed. Later, I changed out the metal hardware with nylon to avoid rust.
