Tubular Keyboard Stand

thingiverse

I have a sturdy A-Frame synthesizer/keyboard stand that I designed and built using my mid 90's tubular A-Frame synthesizer/keyboard stand as inspiration. Previously, I've purchased more parts for it at local industrial metal stores, and I wanted to create more components to customize it further. So I've developed some custom replacement parts that you can print out and assemble your own A-Frame keyboard stand. Update 10/10/2016 Today I just completed making additional synth support bars. I've added a picture of the bars, as well as a photo of tubing being cut. The bars feature a beveled hole drilled near the center, then a 1/4 inch hole at the front with a 1/4 inch rolled pin pressed in. I then cover the pressed pin with some 1/4 inch ID tubing, cut just long enough to protect the synthesizer. Update 07/29/2016 I've included files that allow you to build angled connectors. I've also improved the Tee connector so it's much stronger. I recommend using only Polycarbonate or ABS Polycarbonate alloy for the strongest results. Update I've made the tee clamp fully customizable using SCAD! Many parameters are adjustable with comments to help make them easier to understand. Editing this file allows you to easily create many different types of clamps for various pipe sizes. Just open the KeyboardRackTee.scad file and edit the variables, then press F6 to view it, followed by exporting the STL for printing. Note: KeyboardRackTee.scad uses BoltMount.scad, so Customizer may not work with it. Here are the parts I have made: * Small clamp for joints * Synthesizer support bars * Support braces * Tee clamp Here is what you will need to buy: * Knob (I'm designing one of these soon) * Screws 1/4" 20 x 1" and 1 1/2" * Nuts 1/4" 20 thread * 1.5" thin walled aluminum pipe (available in different anodized colors) * 1/4" thick aluminum bar (for support bars under keyboards or synthesizers) * Various lengths of these bars, rounded on the front and back for safety * 1/4" press pin (prevents keyboard from slipping off support bar) * 1/4" vacuum cap (covers up press pin to prevent damage) Small clamp variations: * A single small clamp supports a keyboard bar * Join two together to make an angle joint (top of an A-Frame) * Join two together using a 1/8" thick aluminum bar, approximately 1.5ft length, to create a brace between tubes and prevent wobble I've included many pictures showing real stand parts and how they're connected. Update: small bracket prints in 1h 37m; tee bracket prints in 3h 32m. OpenSCAD has replaced SketchUp as my preferred design tool due to its greater control over adapting clamps to any size pipes. The first test of the OpenSCAD tee clamp is a success! V2: Updated inner diameter pipe hole, and updated 1/4-20 nut holes to 13.75mm diameter for perfect fit with 1/4" nuts. Short Clamps Fully Tested: The short clamps are printing and working fine. Print Settings: * Printer Brand: MakerBot * Printer: MakerBot Replicator 2X * Rafts: Yes * Supports: Yes * Resolution: .2 * Infill: 18% * Notes: Tee Clamp prints in around 5hrs. Use Polycarbonate or PC ABS Alloy for the strongest results.
