Enclosed Filament Holder

After I made a Lightweight Spool Holder (Which one I like quite a lot) I decided to make another one which will not have one downside of any open like holder. And it is a dust protection. So here is Enclosed one, dustproof. Of course it is much longer to print and takes much more filament as well. But in my opinion dust protection worth those expenses especially if You are not printing spools out very quick. Plus You can put in some desiccant in and you'll get a passive dry box so filament inside will stay dry longer than just being bare outside.

Assembling here is very straight forward. Mounting to MB(Multiboard) , HSW(Honeycomb Storage Wall) or BW(Bare Wall)  is made by using appropriate Bracket. Bracket is made to fit to the MB,HSW,BW by M4 countersunk screws and M4 Fittings/Snaps. 

Here is a list of Hardware You will need beside of 3D printed parts of the model:

To Mount On Bare Wall: Depending On what kind of wall You are going to mount You will need: 4 to 8 pieces of 4mm Countersunk screws (for wood wall) 4 to 8 pieces of 4mm Countersunk screws and wall plugs (for concrete wall) 4 to 8 pieces of 4mm Countersunk bolts/screws and drywall ankers (for drywall)
To Mount on Honeycomb Storage Wall (HSW): 4 to 8 pieces of HSW Threaded Insert for M4 Nut & Bolt 4 to 8 pieces of M4x12 Countersunk Bolts and Nuts
To Mount on Multiboard: 4 to 8 pieces of M4 Heat Insert Snaps. I used a Weight Bearing ones but I'm sure either of them will hold just ok. 4 to 8 pieces of M4 Heat inserts 4 to 8 pieces of M4x10 Countersunk Bolts    Small DIY Hack if You don't have Heat Inserts or don't want to use them here.  You can use a M2 (or M2.5 not sure which fits better you need to try first) Heat Insert snap without Heat Insert. And use a M4 wood screw. Only advice here is to use all 8 for secure fit or for Top 2 holes drill holes in wall and use  a Long screws and wall plugs to secure them Top 2 fittings.
Hinge Rod As a simplest and cheapest here, You can use a piece of filament. But I would suggest  as a better choice to use something like 2mm garden wire or even better a 2mm steel rod.
For Magnetic Stopper 4x 12x3mm Magnets (Optional) 2x M3x16mm Screws (Lid stopped top hole) (Optional) 2x M3x12mm Screws (Lid Stopper bottom hole)
PTFE Coupler PC4M10 This is optional as if You don't want to Use a PTFE tube You can feed naked filament Through hole provided. Or just put PTFE tube into hole and secure with some Blu Tac or something similar.
4x 608ZZ or 6085-2RS Ball Bearings
If You choose a Windowed version You will need a 2mm (or less) Clear Acrylic or analogue sheet  90x100mm. I doubt You will find this exactly size to buy. I did use a 150x100x2mm ones and just cut 150mm side to 90mm with  utility knife.

Assembly Instructions

Assembly here is very simple.

1. Assembly of Rollers:
   
   - Print 4x Halves of Rollers and 4x of Roller assembly Pins. 
   
   Snap Them Together. For better fit a few drops of Superglue here is recommended
   
   - Put on both ends 608-zz or 608-2rs Ball Bearings
   
   
   You can use something like Electrical Tape to give Rollers better grip and softer surface
    
2. Push Rollers in place until they snaps in:
    
    
3. Mount Magnets and Magnet Stoppers:
   
   - Push in 12x3mm Magnets in to magnet Holes securing them in by a drop of superglue inside the hole. Preferable with same polarity (not critical)
   
   
   - Mount Stoppers to the Bottom Main Body of the holder with 3mm Screws or with just a Glue if You like to go that way better. If You are mounting them by using screws important here is to use a M3x10mm on the TOP screw hole and M3x8mm on Bottom Hole. 
   
    
4. Push another 2 magnets into magnet holes on Top Lid's inner surface by securing them with drop of superglue. But here is very important to make sure you are fitting them in in right direction. So check magnet polarity first without glue. 
    
5. If You are building a Windowed version, take your prepared clear sheet (acrylic or glass) and glue it into the slot from Lid's inside. 
    
6. Mount Main Bottom Body and Top Lid together with your desired Hinge Rod (Filament/Wire or Steel Rod) by pushing it all the way through the hinge hole.
    
7. Mount corresponding wall bracket to your Type of wall by using screws/fittings/snaps. To mount on Bare Wall just use any of given Brackets. Multiboard or HSW , just use a screw Holes to screw it to the wall. 
    
8. Slide Holder into the Bracket using Slider Rails from Top downwards
    
9. Screw in PC4M10 PTFE Tube coupling 
   
   and push PTFE tube Through it so PTFE tube comes out for about 1cm into inner compartment.
   
   
   Or use any of your desired Filament feeding options.
