This design is meant to enable you to use a non-MakerBot spool of filament with ease. It uses the existing filament guide tube to make sure that there is as little stress on the printer and filament as possible.

The V2 file has been redesigned to accommodate the MakerBot large 0.9kg spools. No more switching back and forth between the cartridge system and the side-mounted spools!

The old design interfered with the gantry system on some 5th Gen units and with the Replicator+. The new V2 design no longer interferes with the gantry and will work with ALL 5th Gen and Replicator+ printers.

It sits on the left side of the 5th Gen Replicator or Replicator+ and swings into place easily. This design enables a non-MakerBot spool to be used easily without increasing the overall footprint of the machine by much.

We designed this specifically so that we could use 3D-Fuel filament.

Can you increase the size of the lip on the spool?

Best thing I've printed yet!
38 hours without a single issue so far. V2 is a perfect design. Thanks!!

Which one is the version for the Makerbot Replicator + plus?

If you go to "Thing Files", it is v2 (the more recent upload)

I printed it, but I just have not tested a reel on it. However, I can confirm the new version does not get in the way while printing...at least with what I have printed. A very worthwhile tool to print for your MB Rep 5th ed.

Printed the V2 version and it clips nicely to our Replicator +. Problem is that it prevents the gantry from moving forward or back. In your description, you said you re-iterated the design to work with the Rep+ model. Perhaps the file is incorrect? Just wanted to put it out there that the V2 files as it is does not work with the Rep+

Edit: I think when I printed from my phone, though I clicked the V2 version, it printed the other version with the clip. I'm going to take a look at this again and report back.

We printed one of these for a friend's unit. It clips to the Replicator 5th gen frame very securely, holds spools from several different manufacturers and creates a better filament delivery path than stock. However, the part of the top flange that hangs below the rail impedes the y-axis. There are two screws on that carriage that rub as they pass. We filed a chamfer (45 degree angle) on the underside of the top clip. This clears the screw heads.

Further description: If you don't understand where we mean, orient the thing as a letter "S" with the rounded part at the top. On the upper-right side, you will see the flange that comes down and curls inward. The outward-facing corner is rounded, but the inward-facing lower corner is sharp. It is this sharp corner that we chamfered.
