CR-10s Cable Strain Relief Bed Restraint by pr0ph3t1c

Last crawled date: 4 years, 7 months ago
This combination cable strain relief and bed restraint is for the CR-10s 4 but may work with other CR-10 printers. It works with stock hardware.
It accepts a 7mm nut press fit and allows the spring to sit flush inside. The modification adds significant tension to the spring but removes wobble from the bed as the nut and spring tension combination fastens the the unit to the aluminium bed.
This provides a solid raised edge that secures the glass bed without the need for clamping mechanisms which distort the aluminum bed. It should be paired with the CR-10s 4 bed restrains I designed as well which I still need to publish.
Installation
Installation will require the user to perform the following
press fit 7mm nut into place
insert stock bed scew through aluminum plate and secure to the strain relief/bed restraint via the press fit nut
insert spring from under side of strain relief over the screw that has been feed through and secured to the nut/fastener
insert assembled unit into the bed mounting plate
apply pressure to the spring by squeezing the assembled unit and attach the bed level adjustment nobs.
Just another strain relief
This unit is firstly just another strain relief for the well documented and solved issue on CR-10s. As a whole when paired with the mentioned bed restraints this unit isolates the spring from the bed and removes the majority of:
bed vibration
bed wobble from the springs
general bed mobility
bed distortion and warping
Value Adds
In turn prints will benefit with:
better precision
no noticeable layer distortion
better print adhesion
better print bed heating via less distortion presented when clamping
Next Steps
I need to provide:
images of the printed part
images of press fit fasteners
competent assembly instructions
refine and iterate the model to allow for full spring support by slotting the bed mounting plate completely encapsulating the spring, or remove the spring in turn for a hard/rigid mounting solution and or stepper motor mounting solution which would allow for mechanized/robotic/automated bed leveling.
