I want to design a solution that is adjustable in length and versatile in use. The idea is that you can use the same parts whether you want to place the spool on the table or hang it under the table. It also needs to be able to print on any Bambu model printer, including the mini model. This is the solution I came up with!

Use instructions:

For a single layer, you need:

• At least 2 bases. If you want to make a longer shelf, for example, more than 80 cm, you can print another one to support the middle part. If you are using a small board like the Bambu Mini, you can use a half-base.
• 2 standard-sized 23-millimeter broom handles.

Then, if you want to stack multiple layers, you also need 6 connectors for each layer.

You also need four feet/hooks.

Finally, use the key to assemble all the parts.

Tip: First, print a key and a connector, and check whether the tolerances match the machine. There is a key suitable for PLA and a key suitable for ABS, the latter of which has stronger shrinkage. If none of them fit, you can directly adjust the size of the key in Bambu Studio.

You can use the guide in the original file to locate the screw holes for the brackets.

Happy printing!
