Repairing a Broken Folding Camping Chair with 3D Printing

The broken plastic joint on a folding camping chair can be replaced with a 3D-printed one. I found a design at myminifactory that looks very similar to the one on my chair and tweaked it in Fusion 360 to match the dimensions needed. I printed a test piece to make sure it fits well, then fine-tuned the model further before printing it with 100% infill. I used regular black PLA filament on my Creality CR-10 printer.

Burnt / Darkened LCD Display Repair

A fairly easy way to repair such LCDs that are found in many common devices. I had used aluminum tape to replace the backing, but anything that can reflect a good amount of light, such as a piece of white paper should work too. I had also dipped the cotton bud in thinner to help with removing the adhesive, but any solvent of sufficient strength (such as nail polish remover) should work too. I've even seen others simply using an eraser to rub off the adhesive cleanly.
