BITHOLDER (for 1/4" Screwdriver bits!)

hello you!

I designed this bitholder in 2021 and thought I might as well finally share it with the internet!

The bitholder can hold up to 20 (4x5) bits, two long bits and a magnetic bit holder for your screwdriver. 

notes on printing:

• PET-G 100%!
• The hexagon tolerances are tight but if your printer is up for it the bits will fit snug and snap in to place with use of the little magnets beautifully!
• If your printer has the first layer set too flat on the heat bed you'll probably have to wiggle your bits in but they will fit just fine after I suppose.
• Printing is otherwise straight forward, I use no supports and remove some of the spaghetti by hand twisting a little 3mm drill bit through the holes which works fine!

notes on assembly:

You will need:

• 10x 5*3mm neodymium disc magnets
• 3x 8*5mm neodymium disc magnets
• 3x m3x20mm cylinder head machine screw
• 3x m3 flat nut
• some kind of carabiner
• your bits!

Assembly:

1. Insert all 10 5*3mm magnets in to the middle strip, using a little instant glue in case some don't press fit.
2. attach left and right bitholder sides using machine screws and nuts.
3. press in 8*5 magnets to side body as depicted below:
4. clip side body on to main assembled body using plenty of instant glue. Don't worry if ever any single part of your bitholder breaks you can remove the glued side body, repair and reglue, works well! 
5.  Attach carabiner of your choice and insert bits!

You're all set!

further notes:

• Quick release bitholders with thicker collars will not fit as I do not like them and did not integrate them to be compatible with my design.
• I produced 50 of the bitholders with the middle part lasered out of 3mm stainless steel for longevity last year. They are beautiful and truly 100% functional. If you'd decide to want to do the same make sure to order your 5*3 magnets beforehand so you can measure them precisely as their actual diameter is not 3mm. When creating your dxf from the stl file make sure to adjust the tolerances of the 3mm holes accordingly and talk to your laser person to avoid clearance issues! We made three test versions and got the part lasered so the magnets could be press-fitted.
• the non cnc version (with the middle part FDM printed works just as well but you will not be able to use the middle strip to open bottles, unfortunately! You can try but I wouldn't recommend it. The carabiner hole might eventually break even though I used it for about half a year without failure before upgrading to stainless steel.
• If you're having any issues with assembly leave me a comment I'll get back to you!

Thank you, happy working!
