Introduction: Better Makerbot Replicator 2 Buttons

A more permanent solution to crappy soft buttons for your 3D printer.
I've tried the remote button repair kits and other techniques, and they always eventually fail. Adding momentary switches adds a satisfying click to moving through the menu.
At this point you're probably so frustrated with fixing these buttons, I don't need to tell you how to disassemble your LCD panel.

I used the soldering and electronics tools at TechShop to complete this project!

Step 1: Required Parts and Tools

You will need:
5x momentary push button switches
Soldering station and solder
X-acto knife

Step 2: Bend Momentary Button Connectors

This will make it sit more reliably on the board. Don't worry if the leads on the same side touch, those are already connected.

Step 3: Solder Onto Button Board

I tinned the pad, held the button on, and soldered. Note the direction to solder on the buttons, if any are turned 90° it will be always on instead of a button.

Step 4: Cut Jelly Buttons

Cut about half of the inside of the 5 buttons off to make room for the new buttons.

Step 5: Reassemble and Click Away!

Thanks for a great suggestion! I had switches with only two leads, which made it really easy. Works like a charm.
