Milwaukee Tool Style Bit Holders V6

Milwaukee Bit Holders V6

Description

First to clear up any confusion, this is the 3rd release of these bit holders, with these ones on Thingiverse being version 2. I’m releasing these as version 6 because that’s my internal version structure and it makes it easier to keep track.

Here is a list of what’s new in this version:

  • Narrow box bit holders
  • Chamfered pegs for perfect printing without supports and easier insertion
  • Improved long bit holding (no wiggling)
  • Redesigned the spring on the short bit holders so they are relaxed when bits are inserted. This is important because thermoplastic (3D printer filament) tends to deform or set when it’s in the sun or a hot car or other space. If the spring deforms when there is a bit pressing against it, it will lose it’s holding power. This new design should address that.

After creating my bit trays for the Milwaukee Packout rolling toolbox that could use either the wide or narrow Milwaukee bit holders, I figured it was time to create some narrow Milwaukee bit holders. I already had the model for the wide Milwaukee bit holders over on Thingiverse, so it was just a matter of changing a few parameters.

Rather than stop there I decided to make a few tweaks to the holders. First I shaved off the bottom portion of the mounting peg to make it easier to print the holders with no supports. Then I tweaked springs on the the tall holder to hold the bits better. Finally I redesigned the springs on the short holder so that they relax when most impact bits are inserted.

Instructions

I’ve provided 5 different files. The first is the openSCAD model, if the four other STL files don’t meet your needs you can create new ones by modifying it. If you need help reference this page on customizing openSCAD models.

The next two files are for the tall holder. The wide holder is used in the wide Milwaukee cases, the low profile Packout bins, and the bit trays for the Packout rolling toolbox. It has 8 bit slots by default. The narrow holder is used in the narrow Milwaukee bit cases and also in the bit trays for the Packout rolling toolbox.It has 6 bit slots by default.

The last two files are for the short bit holders, both wide and narrow.
