Float Switch Bracket

thingiverse

This is a bracket to hold float switches on a rimless aquarium. It could work in other situations where the container doesn't have a large lip. The mount is adjustable allowing you to set the desired switch position. I recommend using nylon hardware for the nut and screw to avoid rust. I've included OpenSCAD files that allow you to adjust the following characteristics: Bracket: length - the longer the bracket the more available range (default 60) width - sets the width of the bracket (default 25) switchRadius - how large the hole is for the switch (default 5) switchArmLength - how far out the switch can be heald (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 the 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: .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. I later changed out the metal hardware with nylon to avoid rust. Here it is installed. I later changed out the metal hardware with nylon to avoid rust.
