Discription:

I have remixed the model to prevent my Allen keys from rotating in the holder. 
With a tolerance of 0.6mm from the original model, I can insert the keys into the smaller adjacent slot or freely rotate them in the designated slot.

Furthermore, I have made minor improvements such as rounding off edges and aligning the labeling.

To account for variations between printers, I have conducted tolerance tests for 4mm wrench. 
My remix has a tolerance of 0.15mm. 
With my printer, the Allen keys easily slide into the openings with gentle pressure.

If you desire a different tolerance, please let me know, and I will create the corresponding model accordingly.
