After purchasing Original Prusa Enclosure I noticed that there is a lot of headroom considering printer build volume height. I made couple of measurements to discover that there is just enough space to comfortably fit a spool of filament.
And there it is, after a few failed attempts and changing approach couple of times i created the ultimate Prusa Enclosure spool holder with additional containers for silica gel, that will allow you to store up to five 1KG spools of filament to use right away in the printer. And also with silica gel and heat from printer this is great environment to keep your spools dry. And all that without any extra volume outside your enclosure!
The hardware used to build this miracle of craftmanship is really basic and cheap:
- 1m of aluminium pipe with 20mm in diameter (we'll need to cut it in half)
- 20 x 608-2RS bearing
- 10 x M3x12 screw
- 4 x M3x15 screw
- 14 x M3n nut
- around 30cm of PTFE tube (we need 5 tubes with around 6cm in length each)
Assembly is pretty straightforward, there are 2 main aluminium pipe holders (left and right) which carries all spool rollers. Those are mounted via 6 M3x12 screws. On pipes you can fit up to 5 spool roller assemblies.
Spool roller is built from 2x spool roller side and and spool holder roll and they are connected together by 4 bearings. Everything here is held together via press (friction) fit.
Additionally there are 2 silica gel containers that fits nicely on top of pipe holders along with covers.
To make sure that filament can be dispensed without any side friction there is special filament guide that makes sure that roll unfolds the same way all the time. The filament guide is built from 3 parts connected via M3x15 screws. On guide there are 5 holes for PTFE tube that will ease the angle of filament during printing to avoid any friction and stress on filament. Everything is mounted on enclosure with M3x12 screws.
I'm using this setup for a few weeks now and it works flawlessly. I'm really happy with this idea and design and hope that you will be happy too! This is my first such a complex design as i'm learning to model and own my MK4 printer only couple of weeks, so please don't roast me too much for any design flaws that I might have done :)
Also if you liked my work please consider leaving a like, because I've used quite a lot of material prototyping this and maybe, just maybe I'll manage to get some prusameters in return :)
