voltage control and measure box - speed controller
Description
This A Small Box That Can Hold A Dc Dc Converter, Voltage Display, Toggle Switch And A Multiturn Potmeter. I Designed This As A Speed Controller For A Dc Motor Used In My Filament Extruder. See Http://Www.Thingiverse.Com/Thing:677144 But It Can Be Used Everywhere You Need A Voltage Display Or Adjustable Voltage . There Is No Bottom For It. Just Mount It Somewhere. Printing: No Support Needed. Fill Value Not Critical - I Used 90%. Layer Height Not Critical. I Used 0.3Mm For Faster Print, But You Can Clearly See The Layers. If You Like To Use It As A Voltage Controller, You Need To Buy A Multiturn Potmeter Of The Same Value As The Potmeter Present On The Dc Dc Converter Board. Most Cases This Is 10Kohm. Unsolder The (Blue) Adjustable Potmeter From The Pcb, And Wire The Multiturn Potmeter In. The Toggle Switch Can Be Wired In The Output To Disable The Output. The Dcdc Converter Pcb Is Hold In Place With One Or Two Pieces Of Insulated Wire Or A Tire Wrap.

But Should Have The Correct Dimensions. And Likely The Links Will Stop Working In A Few Weeks Anyhow…
