When you (for whatever reason) have uncoupled your hotend cables from the bowden tube you will find out rather soon that some sort of cable guide / strain relief is necessary to make everything look neat'n'tidy.

Here's my solution - a combined cable strain relief / bowden support bracket that simply snaps on the upper X carriage guide roller axles.

Update - due to request I uploaded a .step version for you to tweak as needed

Update - added a version with a "trigger finger" to work with my BT remote switch
