Quick-fit Extruder mount and X Axis for the Printrbot 3D printer #30DoC day 5

For Day 5 of  30 days of creativity ( #30DoC ) I give you another addition to the Quick-Fit family, here is a Quick-Fit X carriage and mount for the Printrbot. Designed for any extruder's that can go on my Quick-Fit X carriage.

Mount with 3 LM8UU linear bearings and 4 x M4 bolts rather than the original 2.

Bad photo, but you get the Idea.


I have upgraded the dual bearing X Axis on the original Printrbot to a 3 bearing design, It should now perform better and be more stable doing this.

Above is the new design, below is the original - Note you don't loose any X axis movement or printing area with the Quick-Fit mount.

I'm calling it the PINKrBot for obvious reasons, if you need some ultra bright Pink PLA, Faberdashery have just launched an insanely bright and fluorescent range for the summer - * Punk Star Pink *

Files for the Printrbot Quick-Fit X carriage are up on Thingiverse Here.

While I was in the middle of drawing this for the Printrbot, a quick-fit adapter for Huxley was requested, as they share a vertical X arrangement, it should be possible. I'm just a little worried it will use up all of Huxley's X space!

#30DoC Day 5 - for inspirational work from around the world

I'm not obsessed with Extruder's and X carriages, I just really like them :)

 ** - Also Awesome things are happening over at the Unfold-Fab, right now, do take a look.

Thanks for looking, let me know if you have a Printrbot (built up) and also if you print one of these.

More tomorrow.

Cheers,

Rich

    When I hung an extruder from a plastic right angle bracket like that the nozzle wandered in Y during the first few layers. The heat from the bed caused it to flex due to differential expansion.

    That is why I kept the axis flat on Mendel90. Have you had any problems like that?

      I have not seen any problems like that yet with the original bracket/design or this replacement, I am only printing with PLA on the Printrbot, some aspects of the design feel wrong, but it does manage to work quite well and give decent print results for such a mechanically simple printer, it's still early days and I don't use it as much as I should.

    Thanks Rich! On my enormous backlog of things to post and react to is a reaction on you ceramic prints and your paste extruder design. Soon, promised :) In the main while, your fired ceramics looks fantastic!

      Thanks, I'm going to do more with Ceramics and seeing your new work is making me want to learn a lot more about clay printing, I can't wait to see more about the screw extruder, it looks so neat and compact.
