work in progress:
I have been working on a clean way to mount an spool and extruder together. I took the standard printrbot extruder and the bowden adapter that many of you have .. and mocked up a quick wood version. I tapped the whole that supplies the filament to the extruder so I could insert a bowden tube attachment. I really feel that having a small run of hose on the rear side of the extruder helps to negate any kink in the line as it pulls in filament. Here are the key problems I addressed when building my setup.
- Allow the filament to follow its natural curl.
- Keep the Bowden tube as short as possible
- provide the filament into the extruder with the least amount of kink.
- Reduce as much resistance to the spool in both directions.
My design has a universal mount on the top that will support fans for the extruder and I envision anyone could make simple adapters for any extruder out there...
Side pieces without the logo's fit better and require less filament to print. I will be modeling a way to connect modular so you could connect them together to build an array of spool holders for multiple extruder setups.
PLEASE PUBLISH YOUR MAKES!!!
meant for use with
20142411 - added 40mm Fan mount and Printrbot ALU extruder mount
- Added updated two part base- just print twice.
- Sides with no logo fit better and use less filament
20142411 - replaced printrbot extruder mount with stronger mount
20150116 - Added modified printrbot extruder mount, it fits the new double gear extruder. Added printrbot ubis adapter for a bowden fitting 8mm threads
20150201 - Added stronger version of Printerbot exturder mount
