Intro: Universal Cable Shortener
The Cable Eater is a must have to reduce the length of a long cable
that runs off your desk and tends to be crushed by the wheels of your desk chair...
I designed this so i can keep my headset wire safe (2 meters long and 3mm thick), and thanks to it, I transformed my 2m long wire into a 30cm long !
Length gain : up to 99% with a standard 3mm wire !
See Step 5 to download the model and follow the print instructions.
Step 1: Place Your Cable
Take the A part, and put your cable in the center
Step 2: Secure It
Block your cable using part B, snap-fitting it on the A part pivots.
Step 3: Cover It
Snap-fit part C pivot to the part B center hole.
/!\ Make sure your cable is passing between the 4 little 'teeth' of part C /!\
Step 4: Just Roll and Enjoy It
Rollup your cable by holding Part C in one hand (part C should face the ground), while turning Part A CLOCKWISE (turning the other way might damage your cable) till the desired length !
To unroll your cable, do not turn the parts, it's not necessary. Just hold the 2 strands with both hands, and pull.
Step 5: How to Print It ?
Working with PLA, but ABS with its flexibility might be easier to assemble (didn't tried yet).
As there are some snap-fit parts, I would recommend to print at low speed (40mm/s and 25mm/s for small perimeters).
For a smooth finish and a tight fit, prefer 0.1mm layer height, but 0.2mm should do the work.
About the infill : As the A and C parts are pretty flat and large, you may want to keep a high density (75-100%). However B part infill can be reduced to 50%, but keep in mind that this piece will need to be strong and a bit flexible (mine was printed at 100% PLA, it's quite strong but not very flexible).
Heated bed is recommended for PLA to avoid wrapping issues.
Printing time (0.1mm - 40mm/s - 75%) : A part : 2h30 B part : 15min C part : 2h15
Standard version diameter : 10cm.
Small version : 7cm.
