Magnetic Bit Driver Handle

Over the years I have collected a lot of bits in different forms and sizes. But without a bit driver they are pretty much useless. Therefore I have designed this Magnetic Bit Driver Handle.
 

Features:

• Can be used with every 1/4'' (6.35mm) standard bit
• Bits are hold in place by a Ø4x2mm magnet
• The clip-on endcap rotates for easy operation
• Two small standard bits can be stored in the handle
• Printable in multicolour or single colour (so, MMU/AMS is optional)
• Only needs 23gr filament
   

Print preparation:
Make sure that your print bed is clean and grease-free and use a quality brand and dry filament. A quality filament is necessary because the seat for the magnet has tight tolerances.
 

Print settings:
Use the 0.2mm standard settings for everything. Support is not needed. A brim for the handle is recommended to increase the bed adhesion. Set the wall number to four for a robust print. 12% gyroid infill should be enough.
See my 3mf print profile (Orca Slicer or Bambu Studio) for details.
 

Assembly:

• Press the cap on the handle. It is a simple and removable snap-fit.
• Place a Ø4x2mm magnet on the end of a bit and put the bit in the handle.
  
   
• Place the other end of the bit on a stable surface and hit the handle slightly with a hammer.
  Recommendation: Use my dead-blow hammer for this.
  
   
• Now the magnet is pressed into the handle and your bit driver is ready to use.

The magnet can easily be ordered anywhere on the Internet. Just make sure you get the right size: Ø4x2mm. 
You need one magnet per handle.
