This is a simple model to make the small components tester easily accessible from the wall at my work bench.  You can either use 15 x 2 mm magnets (Some difficulty as the upper magnet will be repelled by the lower magnet and must be secured with something like double sided tape so it doesn't pop out.  Worked fine for me but your results may very).  You can also just place the metal plate included with the device on the front flat face.  I just wanted a super simple solution to keep the manual, extra tips, and device all together and easily accessible, no frills.

Since it's a pretty simple model it may not matter but spacing and tolerances are designed with 0.2mm layer height and 0.45mm parimeter thickness. 

Step file is included if anyone wants to remix although it's a fairly niche tool so I can't imagine many people will be printing it.
