10 inch Rack 1U Finger Duct

This is a simple finger duct for a 10 inch rack consisting of 2 parts: the fingers that attach to your choice of rack system, and a cap which fits over the end of the fingers. While you can certainly just sit the cap on the fingers, there are 6 x M3 screw holes with nut cutouts that you can use if you have particularly stiff cable that may push against the cap, or otherwise be difficult to hold in place.

Printing

No special instructions. Most flat runs are 4mm, and in my case were printed at 0.28mm to maximize speed. The cap should fit with some friction, but I'd certainly recommend using M3 nuts and bolts once you've decided how you want to run your cables.

For the split version added in update 3 you will need 2 x M3 nuts/bolts/washers to attach both halves. In addition to the obvious benefit of being easier to print alongside other parts on a small bed, split fingers also means that you can remove old fingers, and install new fingers on an already populated rack without having to unplug cables already run through the center.

Updates

1. Updated the cap with matching cutouts to the fingers so as to waste less space. I've also rotated the fingers to be more easily, immediately printable across a small bed. Unfortunately though, my printer's bed heater finally died, so I'll update the photos next week.

2. Updated the fingers to increase the depth of the slots as well, since some devices (most notably, the UniFi mini gateways) have angled power plugs which cut pretty close to the bottom of the old slots.

3. Added a split version of the fingers so that both the cap and fingers can be printed at the same time more easily.
