i3 duplicator printbed backup wheel

I designed a custom bearing replacement for the print bed surface on my i3 Duplicator, and I'm sharing how I did it. The problem: My bearing was failing, and I needed to replace it. Since new bearings were in short supply, I decided to take matters into my own hands and design one myself. I started by researching existing designs for custom bearings, but I couldn't find any that fit my specific needs. So, I decided to create my own design from scratch. Here's a step-by-step guide on how I designed the bearing: Step 1: Measure the print bed surface I carefully measured the print bed surface to determine its dimensions and material properties. Step 2: Choose a suitable bearing material Based on my research, I selected a durable plastic that would withstand high temperatures and friction. Step 3: Design the bearing shape Using computer-aided design (CAD) software, I designed a custom bearing shape that fit perfectly onto the print bed surface. Step 4: 3D print the bearing I sent the design to my 3D printer and waited for it to print. The result was a precise and accurate bearing that matched my design exactly. The outcome: My custom-designed bearing worked flawlessly, allowing me to continue printing without any issues. I was thrilled with the results and proud of myself for taking on the challenge.
