Abstract[edit | edit source]
This project is an upgrade on the current Recyclebot v5 cooling section. The previous design uses a top-down approach at cooling off the filament post extrusion, this was rather annoying to initially feed the filament through. To get rid of that issue, I created a way for the fans to permanently mount to the bottom and have the air funneled to the filament via a 3D printed shroud. This solution makes it easier to initially feed the filament through, while still gently cooling off the filament and the aluminum trough itself. This project is Appropriate because it is part of a machine that can be built for less than $600 and make filament that is comparable to that bought from a supplier. This fulfils the need for people to make their own filament at home and reduce costs and waste. Currently the MOST research group and the Open Source Hardware Enterprise use Recyclebots to make their own filament for research purposes and this upgrade will make it easier for them to do so in the future.

Tools needed[edit | edit source]
- MOST Delta RepRap or similar RepRap 3-D printer
- Allen Wrench (For M5 and M3 Bolts)
- Soldering Iron and Solder
Skills and knowledge needed[edit | edit source]
Technical Specifications and Assembly Instructions[edit | edit source]
- Print all parts ~ 5 hours
- Start Assembly ~ Should take about 10 minutes.
- Mount the fans with stickers facing the Fan Shroud printed parts with (2x) M4X25 bolts in each corner, thread into the plastic part.
- Slide Fan-Shroud Assembly onto the aluminum trough.
- Assemble the Trough Holders with (4x) M3X16mm bolts and (4x) M3 Nuts, (2x) for each holder.
- Screw Trough Holders to Recyclebot frame, careful to align the fan shrouds where you want them. The trough holders can get in the way of sliding the fan shrouds back and forth.
- Place trough, with fans on it, on top of the trough holders that are screwed into the recyclebot frame.
Common Problems and Solutions[edit | edit source]
- Make sure to align the fan shrouds to avoid the trough holders. The holders can get in the way of putting the shroud all the way on.
