We're excited and proud to launch Thingiverse Apps. Learn More about what this means to you.
This will work for both V2 designs (with & w/o string tension)
In response to multiple requests I have developed this GT2 timing belt conversion for the X axis of the Printrbot Simple. This thing is similar to my original http://www.thingiverse.com/thing:191706
For anybody having trouble printing these parts I have uploaded a 2014 version to Shapeways if you would like to order them online. http://shpws.me/rbxE
This is marked as a work in progress. If you have a success (or failure) please let me know. Feedback is greatly appreciated.
For discussion of the evolution of this project please refer to http://www.printrbottalk.com/forum/viewtopic.php?f=106&t=5697
Special thanks goes out to ahaer for all the R&D work!
Just a "head's up"
In order to replace the X axis motor plate, ALL sides of the machine will have to be removed. This includes sliding the Z rods out of the base plate. You don't have to remove them from the top plate, but they will need to come out of the bottom plate.
The dis-assembly is more scary than difficult. Simply be mentally prepared for a complete dis-assembly of all sides and it won't be too bad.
Your efforts WILL be rewarded, and you will not want to return to the string drive.
One tip on threading the belt: Using a 4 inch length of sticky tape cut to the same width as the belt, stick one side to the top of the pulley, and rotate it around until it comes up on the other side. Then stick the smooth side of the belt to the tape and carry on turning it through, pulling gently on the end of the tape.
