001-Storage Base Introduction

• The foundation of the kit, please ensure Component No 001 is completed before upgrading other components
• Component No 001 consists of 2 oversized drawers and TPU stable feet
• Developed entirely based on the A1 printed model, it fits perfectly after installation (thanks to author vajojajo for the open-source A1 model)
• I will provide detailed installation instructions for each component, please read the printing instructions carefully before printing

Printing Instructions

• There are many large models in this kit, with a certain risk of warping (especially in winter). To prevent print failures, I have made corresponding adjustments to the printing parameters, please do not change them at will
• Due to the huge printing volume of this kit and too many plates, it is released in 5 parts to avoid confusion. Players can print as needed
• PETG HF is used for printing by default. If you are concerned about warping, you can also use PLA with lower shrinkage for printing, but the corresponding printing cost will also increase
• In addition to the parameters, to avoid printing failures as much as possible, players must complete the following tasks before printing
  • Clean the build plate
  • Apply glue
  • Do not blindly increase the filament cooling parameters
  • Increase bed temperature by 5 degrees
  • Ensure filament is dry (even newly opened ones should ideally be dried once)
• If slight warping occurs, it's fine. An error of 1-2mm will not affect assembly (don't pursue perfection too much, let yourself off the hook)
• There's no need to discuss whether to use an enclosure. This kit was designed for players who don't want an enclosure. I myself have used 3 different enclosure methods, and the experience was not ideal. In the end, I chose to remove the A1's enclosure and added an enclosed P2S
• Finally, real photos and installation instructions are attached, and a PDF version is available for download for easy viewing on PC
