LTT Precision Bit Set + Case Extension (bản mở rộng đáy case)

I got a LTT Precision Bit Set + Case as a gift to replace my older, cheap tool set. While the set included a much nicer driver and easier method to get the right bit, it left me wanting for space to store other tools I typically use at the same time.

This extension uses magnets to hold on the back of the case purchased from LTT. 

Also designed a lid that can be used to cover in case I want to transport it separate from the LTT case.

The magnets I used were marketed as 4mm round x 2mm thick, but in reality where only 4mm round x 1.75mm thick. I printed in PETG, and so made the holes small enough to require the magnets to be pressed in without requiring glue. Make sure to install in the right magnetic orientation to work with the case.
