Bowden Tube Holder / Guide for Ender 3 Series Printers with a Micro Swiss All-Metal Hotend

thingiverse

Description: I designed this bowden tube holder/guide to fit on Ender 3 series printers (I have an Ender 3 v2) with a Micro Swiss all-metal hotend. Functionally, it straightens out the bowden tube as it enters the cooling block, and strengthens the connection to prevent excessive wear on the weak Micro Swiss bowden collar. Rationale: The bowden collets that come with the Micro Swiss all-metal hotends for the Creality CR10 and Ender 3/5 series printers wear out fairly quickly. The teeth on the collet are also pretty shallow... only a couple mm from the bottom of the collar. This allows the bowden tube to move around quite a bit side-to-side, which puts extra stress on the bowden collar. Eventually, the worn out collet will allow for vertical movement, which affects retraction, and ultimately print quality. See this video for an example of a worn out collet: https://youtube.com/shorts/eQYFQ8VhdLU?feature=share The holder/guide I designed is intended to prevent this from happening. I used the hotend cable chain connector that was (re)designed by Tobi0892 as a base (previously designed by diogosantos88), and altered it to be used for this purpose. Parts required: PC4-M10 pneumatic fitting for bowden tube (x1) - This part will screw into the top of the holder/guide. You will feed the bowden tube through the pneumatic fitting, then into the cooling block collet, as you would normally do.
