Modular Filament Drawer 20mm GTV H45

Main points:

• 20mm PVC pipe for front, middle, and rear supports, while keeping the point of contact with the spool in the same place.
• Rear support made smaller on the bottom, to prevent scraping.
• Front and middle support width reduced to accommodate thicker rails (they claim 12.7, but my measurement shows 13.2, original design made for 12.5)
• Optional Voron - style M3x5x4 heat set inserts for mounting rails to the frame (I couldn't find short enough M3.5 self-tapping screws)
  • Each drawer needs 8pcs M3x4mm OR M3x6mm BHCS with washers for attaching rails, and for connecting drawers together you need M3x8 BHCS or SHCS 6pcs when connecting side by side, 4 when placing one on top of another.
  • So you only need 3.5x16mm, (rails come with some, but it's not enough), you will need additional 10 per drawer, and some for screwing into the shelf.
  • Note 2 sets of holes in the frame, one for connecting to each other, another for countersunk screws to attach to the shelf.

I used:

600mm GTV H45 drawer rails from amazon.se

20mm cable duct pipe from Biltema.

I couldn't find 3.5x10mm wood screws, so I remixed the frame to use m3 heat set inserts. If you don't want to use heat set inserts - print the frame from the original design, it fits the rails. 

There is an existing metric remix, I haven't printed it as it was also changing the width, and some comments mentioned that it was scraping at the back, and the models haven't been updated since. So I decided to make my own remix. I haven't printed the other one so I don't know if they are compatible.
