Holder for Harbor Freight mini diamond file set.

I've got the 10pc diamond needle file set from Harbor Freight, and it comes in a cheap little plastic holder which works, but isn't great. I decided to get a little fancy and print up a holder, and then got even fancier and designed it to work like a "lazy susan" and turn.

All you really need is the top piece, but if you want to have the turning "lazy susan" design, print out the fixing screw and the base, and find 1/4" balls. I used airsoft BBs as I've got a bunch on hand already, but you could use steel ball bearings if you wanted. I've also got small cutouts for rubber feet of about 1/2" (12.7mm) so it's easy to locate them evenly around the edge. Why? I happened to have three spares on hand and thought it'd be good to not have it sliding around my desk.

Since the design is parametric, it's easy to change the size of the bearings, so I also created a version designed for use with 0.177" (4.5mm) steel BBs, if you happen to have those on hand.

I've also added provision for a Inexacto hobby knife but it'll also work with a larger Xacto handle (or, for that matter, a smaller one) or a Sharpie or most anything. I love the Inexacto design and have probably printed 10 or so at this point.

Things in the last photo:

• This HF diamond needle file set holder
• Better dial for MPSM
• Velocity stack for Noctua 40mm
• MPSM WK9.1 extruder base with access to set screw
• Ugly little holder for cheap thermometer/hygrometer
• MPSM fan shroud with blow ring
• MPSM filament guide
• Large carrying handle for MPSM
• Rude extruder spinner for MPSM
• Inexacto hobby knife holder
  There's actually three of them in the photo, one hanging from a magnet on the printer, one in the middle of the file holder, and one in the crappy little green holder in the back that I never bothered to post.
• Rude gnome
  A test print from a while back that has found a home on top of the printer
• A crappy inexacto/sharpie holder that I never published
• A cool little painting I got from Sedona, AZ

  Print Settings

Printer Brand: Prusa

Printer: i3 MK3

Rafts: No

Supports: No

Resolution: 0.15

Infill: 20%

Filament: Hatchbox ABS blue
Notes:

ABS likes to warp, and in my first print (given to a coworker) the outer edge of the top pulled up and although it worked, it didn't look as good, so I reprinted with a brim which prevented the warping/pull-up. Other than that, there shouldn't be anything fancy about the print, and I didn't need supports. Everything should import in the right orientation for printing as well.
