Creality Space Pi Filament Guide

I put this together in Tinkercad because there were a lot of PTFE tube adaptors but none of them did everything I wanted. Hopefully this will help others. 

The bottom nut is rectangle to fit and lock into place between the Space Pi frame ridges. It also has a large oval cone to help catch and guide the filament into the PTFE tube. 

The top bolt is design to work with a 10mm or 6mm PTFE connector and has ridges around the edge to make it easier  to grip and hand tighten. Please ensure that your PTFE coupler is fully threaded into the top bolt to ensure the filament won't catch any edges and get stuck. Threat the coupler into the top bolt BEFORE fitting to the dryer as excessive force could cause the threads to snap off. 

PRINTING TIPS.
Use PTEG filament or other heat resistant material. Do not use PLA as the heat from the Space Pi could cause the PLA to deform and break.  If using ABS make sure and account for shrinkages as the part cools, this could result in the threaded parts not fitting.
I printed in  0.1mm layer height to make sure the threads are as clean as possible but 0.2mm could work also. Print the top bolt part as shown in the images to avoid any supports interfering with the finer threads for the PTFE coupler.  
Feedback is welcome. Enjoy.
