Pi Torrent Nano

Update : Added STEP files

Design

I have tried to make this as simple as possible to print. The only part that needs supports is the main case. I use Tree - Organic supports as they are easy to remove and don't take long to print. All the other parts have been designed to not need any supports.

Any screws needed will be listed in the parts needed/assembly section. I have designed this without heat sets as I don't think it is necessary.

I have included the Fusion360 files so that you can make any changes you might deem necessary. I am no pro on Fusion360 so sorry if the file is a little messy. If you cannot decypher my methods let me know and I will see if I can help. 

Parts

I have included several different parts so I think I better explain

Main case - Need one of these, its the main part (needs supports)

Sled - 2 different versions :  Pi 5 only with fan mount version (40mm fan - Noctua A4 40mm fits perfect). Also a version for the Pi 5 with the Pineberry NVME bottom shield. Depending on your printer it might need supports for the fan area.

Shield - for Pi 5

Rear Cover - for Pi 5

Front Cover - One version at the moment but at least one more is coming soon.

Feet - front and back feet, They are slightly different from each other so check them by fitting both.

Screws - M2.5 for fixing the Pi to the Sled and either M2.5 or M3 6mm for fixing the rear cover.

Assembly

Fix the Pi to the sled using M2.5 screws. Fit the plate over the ethernet and USB ports and slide the sled into the main body. You will have to flex the sled from the front of the case to fit over a bump. You will know it is seated properly because the edge of the sled with be flush with the rear of the main body. 

Then screw the rear cover in place and snap the front cover in place (it will be tight)

Printing

I have printed this with both PETG and PLA. I would recommend that you print the sled part in PETG as it will be in the warmest part of the print when the Pi is running. I have printed the sled with PLA+ with no creep or breakdown but your mileage may vary depending on how hot the Pi gets.

General parameters I used are :

• 0.2 mm layer height
• Case, rear panel and shield in a colour you like. The front panel in a nice contrasting colour. The sled does not matter as it will be out of sight.
• PLA, PLA+ or PETG. Recommend PETG for the sled for thermal stability. Feet are best printed in TPU but use what you like or cut out some rubber or felt and glue them in place (the recess will help)
• Speeds and feeds as you and your printer sees fit.

Assembly

First thing to do is to use M2.5 8mm screws to fix the Raspberry Pi to the sled. If you are fitting a fan use M3 15mm bolts and nuts to tie the fan to the sled.

Slide the required panel into the top of the main case making sure to take care of the right orientation. Then slide the sled into the main case. Next is the rear panel which requires 3 of M3 8mm screws to fix it in place. 

Glue the feet in place and finally push the front panel into place on the main case. It has some indent and tabs to keep it in place.

All that is left is to plug in and enjoy your new case and Pi.

I have tried my best to make this as simple as possible to print. Let me know if there is anything that I can improve.
