Caliper, replacement of the battery on AAA.

A vernier caliper is essential in 3D printing as it helps to calibrate the printer and measure ready models during creation. However, electronic measuring devices like this often have a battery issue due to the type of battery used which isn't replaceable. The battery life is also short since the compasses don't completely disconnect from power when not in use. This can be inconvenient, especially when you need to measure something urgently and the battery has died. To solve this problem, I decided to utilize my 3D printer to create a case that would simulate the original design while also preserving its features. However, I needed two small screws for the modification, which I found in an HDD. I also used a small lamp bought for a cheap price to complete the task. The issue has been resolved, and I expect not to change the battery for years even if it's not switched off. While I considered delivering the connector and reading the measurements on a computer, I didn't have the connector and postponed that idea for later.
