Ikea 365 10.6L drybox spool holder and buffer

Unfortunately I could never make the spool rewinder work reliably.  So while trying to switch to a buffer system I couldn't find one that worked for me.  My printers live in a small room and space is extremely limited.  My solution was to make vbretsch's filament buffer fully 3d printable and combine it with GMagician's drybox spool holder.  What you see here is my solution to a drybox, spool holder and buffer combination.

Non-printed parts:
- 12x M3x10 countersunk screws
- 12x M3 nuts.
- 6x 608 bearings (2 per spool holder, 1 per buffer wheel)
- minimum 1 foot PTFE tubing
- 2 pass-through cable glands
- hygrometer https://www.aliexpress.com/item/1005007960824587.html?spm=a2g0o.order_list.order_list_main.149.7e6218021g9kZO

Notes:
- Spoolholder was modified in Blender, no STEP files available.
- Outer Support is angled out to help accomodate cardboard spool + spool
- PTFE tubing is held in the base by friction so the fit is very tight, will likely need to be filed out to make the tubing fit.  
- Central axle needs to be snug, otherwise filament can slip between the wheel and vertical holder causing a jam.  
- Be very careful not to tangle filament when loading other wise it will bind up.  
- Loading of the buffer is not a quick process, not hard but can be tedious.  
- Looking from the front, the left spool feeds into the back buffer and exits on the the right side of the box.
- 5 full winds in the buffer works best for my setup 1023mm between tradrack and toolhead, 4 works but 5 seems to work better
- Smaller spacer goes in the flat side of the wheel, gaps between wheel and bars should be the same.
