Stackable Storage Rack for Shoes and Spools

Inspired by the DGA3DP design (link: DGA3DP model), this rack has modified joining parts and enhanced base support. It can be used for storing shoes or spools. The rack requires a 10mm diameter aluminum tube. For shoes, you can use a tube up to 100cm in length, while for spools, a 50cm tube is recommended for better load-bearing capacity. Each layer can hold up to 8 rolls of 1kg spools. To increase support, you can adjust the thickness of the spool and the tube hole size in Bambu Studio. With these adjustments, the rack can support more layers and spools. Note: Supports are required for the base panel during printing.
