Printer build platform cable management

Cable management clamp for printer bed, to avoid bending and breaking at the joint.  Made the top 5mm shorter than bottom, to ensure you can use steel/PEI sheet that is slightly larger than bed.   I use 310mm sheet for 300mm bed for ease of removal, like on CR10 printers.  Designed to snap on and/or to be used with 2mm zip ties.  Print out of ABS, or ASA because it will come into contact with edge of the bed.  I tried PETG it was working but over time warped a bit, so PETG would not be a good choice for being around high temperatures.   Tolerances are made for high shrinking materials.  Let me know if they work for your settings or you need it modified.  I included a STEP file if you want to tinker with it.
