This is a remix combining two other remixes of a planetary-geared filament guide.

I have a sealed box holding up to five commonly used filament spools at a time which feed out from the side and up to the printer which sits on top of the box. I also have more spools I store separately and use as-needed, which I mount on the standard spool holder attached to the top of the printer and feed downwards. To handle this I needed two guides, one for filament coming from above, and one for filament coming from below. Additionally, I have one of those cheap aftermarket dual gear extruders which raises up slightly from stock, so the upper roller had to be raised slightly.

The original design was uploaded by [FragrantAbyss](https://www.thingiverse.com/thing:3434928) on Thingiverse. This remix combines modifications to the support arm by [lennardrischen](https://www.thingiverse.com/thing:4766101) to make it longer for the dual gear extruder, and also modifications by [inheritthefire](https://www.thingiverse.com/thing:4796833) to mount a bearing lower for feeding filament from below the printer. To fit the two bearings next to each other I also modified the bearing to be slightly smaller on the outside.

CTRL Keycap for [Corsair STRAFE mechanical keyboard](https://www.corsair.com/us/en/Categories/Products/Gaming-Keyboards/Mechanical-Gaming-Keyboards/strafe-rgb-config-na/p/CH-9000094-NA). My wife's CTRL key busted after playing too hard, so I made this using the [Parametric Mechanical Keycap Library](https://github.com/rsheldiii/KeyV2).

There are two versions. The rounded version has a round mount similar to the original key, however I found it didn't have any strength when printed with an FDM printer. The box version should be much more stable and stronger, but I added both here in case someone wanted it.

This is a simple adapter I made to connect the hose connector for my ResMed AirFit P30i CPAP mask to one of those cheap Ozone cleaners you find on eBay (e.g. https://www.ebay.com.au/itm/154431321036). This should theoretically fit any of the masks from the same range (AirFit F30i, N30i, P30i)

Spool holder for standard 1KG filament rolls. I used these as part of a project to build my own sealed filament storage.

When printing, I tacked a couple of support enforcers around the top lip of the holder piece in the middle just to give it a bit of support (I'm new to modelling and didn't think ahead to try and design the holder so it didn't need supports, sorry!). The frame itself doesn't need supports.
