I made this to guide filament through a worn out SUNLU dehydrator opening which no longer held the 6mm ptfe connector. I was afraid to drill out this hole, and crack the housing but luckily I had a 3d printer to print parts for my 3d printer accessories. thanks to this design, It now fits a 10mm ptfe pass through connector. 

There are 4 main parts, I printed them all in PETG, except for one which is made from TPU, and is named accordingly. 

Good luck, and happy dehydrating!

This is a snap together case which is extremely breathable. I added some robust mounting tabs to the end of the model with chamfered holes to fit M3x6mm heated inserts, which allow for a solid mounting solution which can be repeatedly removed and reused. The case itself is fit with plenty of ventilation, as it will be inside the Prusa enclosure with my Mk3s+. 

After 6months printing almost exclusively with PETG, the Rpi4b still has not had thermal issues, and the case has been removed and put back in place numerous times.

I made this to hold the cannakit case, it was my first raspberry pi project, and the kit was the right price with everything include, except one problem- where to put it?  This case holder fits snug on the cannakit case so it wont fall out by accident, but allows access to all the ports for cables and wires, while using minimal filament, and it matches my fancy printer. It is designed to mount to a wall or in my case the outside of my enclosure, which gets quite hot when printing PC, and causes thermal throttling.

Enjoy, and Happy printing!
