Organize the stuff that hangs around your Carvera CNC machine! Utilize one of your unused swing arm brackets on either side of the machine. This design keeps the USB port exposed. Not only that, it includes a peg you can use to hang your tapes. The design is plenty rigid and should not shake around or vibrate while the CNC is in operation, although that partly depends on whether your tools fit snugly. The look is designed to rhyme with the shape of the Carvera itself.

NOTE: The print profile supplied is customized for my personal tools. Your own tool configuration might vary from this one! To that end, please see the attached STEP files which contain blanks for both the left and right side of the unit, as well as mounting brackets and two choices of tape roll holder. Feel free to try my example or toss these STEP files into Fusion or Onshape or your CAD of choice to punch out your own custom tool holder.

If you design your own: please reference the example print profile to see what settings I used. Since the tool holder should be printed face down, I recommend using support on the build plate, set the “top z distance” to zero, and let the part cool after which it should separate easily. This keeps the surface quality quite good and you won't see those surfaces anyway. In the print profile I also show using support modifiers to strengthen the area around the mounting screws. Please open and review those settings before printing your own, as the part is quite sizable and you don't want to waste time and filament with mistakes.

You will need hardware! The screws that secure the plate covers on the side of the Carvera are too short. Additionally you need screws to join the mounting bracket and the tool holder. So what you will need are:

• 2 x socket head cap screws for mounting the bracket to the Carvera, M4 x 20mm
• 2 x flat head cap screws for mounting the bracket to the tool holder, M6 x 40mm
• 2 x nuts, M6 to match the screws

See the attached photo. Drop the nuts into the slots. The countersunk heads of the M6 screws should not protrude from the mounting bracket, since we don't want to scratch the panels on your Carvera. You can of course hack the STEP files in Fusion/Onshape to suit a different set of screws rather than M6. I chose 40mm as those were the longest ones I had and should keep the bracket and the tool holder at a stiff right angle to one another.

If you print in ABS: be aware that both parts are quite long, and ABS loves to warp. Use a solid build plate, a quality adhesive like Magigoo, and preheat your build chamber. Preheating the chamber is one of the single best changes you can make to sure your ABS prints stay flat. 

However, as long as you're not hanging steel plates or bowling balls off the tool holder, PLA should work just fine. If you want to hedge your bets you can always up the infill percentage.
