After 5-7 months of development, I'm now able to travel around the town/country/world with my little folding RepRap ! Which still have a 140x140x140mm build area :D

I started by a folding reprap the size of a Mendel, based on my VertX, then a smaller version more Huxley-transportable, and finally I'm developping this one build with aluminium t-slot extrusions. It's the first iteration of the Folding RepRap.

Some of them are in the github repo / souce files / Mendel size, but as I will have more time to design other things I will certainly publish a redesigned model for nema17 :)

I have been looking for the FoldaRap Mondrain size. I saw it had Nema 17 motors and was 2020 extrusions. Is there a link for the files to be printed for that?

I have a lot of Nema 17 too, but I think you could try. It will be a little bigger but luckily with more holding torque.

Mix a bunch of 20x20 aluminium extrusion, some t-nuts, printed parts...
Voilà  : a Foldable RepRap !


1) Download Sketchup to see the model assembled, folded, and play with it to get familiar with how it's made.

2) Get the latest version of the .stl from the Github repository or export them from the Sketchup source file (with the famous guitar-list's plugin : guitar-list.com/download-software/convert-sketchup-skp-files-dxf-or-stl)

3) Print the parts with your favorite machine (need to be well calibrated)

4) Order the things you need, (look at the BOM), with a preference for local suppliers if you can.

5) Assemble (based on the 3d-model and all the pictures/video on the wiki/flickr)

6) Enjoy to easily travel with your sturdy and foldable reprap :)

Is there anyway possible to use Nema 17 motors with this?? I have plenty of them around so then I would not have to buy more items.

Thanks for a great looking machine! I can't wait to build one!

is there any 3mm filament version of the foldarap?
Has anyone made one?

wayves on Oct 28, 2013 said:

is there an updated version for the sketchup file for the 1.3? got problem with the printed t-nut on the foot...doesnt fit my 20x20 profile...thought of modifying it...thanks

watsdesign on Oct 29, 2013 said:

go to the github repo for the source files ;)

is there a good source for the laser cut parts?

watsdesign on Jan 19, 2013 said:

I can add them to Ponoko if you like, otherwise I'd say any local laser shop/fablab/hackerspace that can cut it for you :)

(replaced some old .stl's, but github is still the preferable location to download all the files)

watsdesign on Sep 15, 2012 said:

replaced the y-end-idler and y-end-motor to match the overall use of M3 bolts

mattwj2005 on Sep 8, 2012 said:

I really want one!

By the way, your kitify site is blank.


watsdesign on Sep 13, 2012 said:

Glad you like it :D

about Kitify, I'm waiting for the first other prototypes before (as I'm still using some salvaged rubber roller, I would need to make a version for the more commons bearings)

watsdesign on Aug 4, 2012 said:

now also on Github ! (thanks to github-for-windows that make it usable for me now ^^)


antpgomes on Aug 1, 2012 said:

Do you have a direct link for the BOM?

Can't find it on the wiki :-[

watsdesign on Aug 1, 2012 said:

Sorry it's on the http://reprap.org/wiki/FoldaRa... ^^'

excellent work!! I've been printing the parts. did u design the front left and front right foot to be very tight? coz Im having a hard time to slot the aluminium extrusion in to the little T-nut like printed hole. Im using bosch extrusion by the way. wouldn't it be a good idea to replace the t-nut thing to a hole that is fixed by actual t-nuts and screws?

watsdesign on Jul 30, 2012 said:

I first used a hole instead of the t-profile, but after having tried it I though it could save some of these costly t-nuts ^^'

I'm printing them with a 0.5mm nozzle and with 1 perimeter, (the gap between the parts and the extrusion is 0.2-0.4 mm from each side so 0.4-0.8 mm in total), it's supposed to be a little tight for these part to allow a push-fit assembly with just one nut+bolt to secure it.
For the hinge that shou
ld slide on the extrusion, they just need to be moved manually for a few minutes until it slide as smoothly as desired :)

(I'm using KJN extrusion, they should be similar to the bosch http://www.aluminium-profile.c... )

watsdesign on Jul 7, 2012 said:

added the y-carriage that I had forgotten, and also a .zip to download all the files at once :)

Spacexula on Jun 29, 2012 said:

Do you have a place where all the stl have been exported?

watsdesign on Jun 30, 2012 said:

Just finished to upload all the exported .stl/.dxf :)

watsdesign on Jun 29, 2012 said:

I export them from sketchup as needed.

And I upload them progressively while printing/validating them now.

(I plan to use only M3 but my prototype use M3 and M4, so I need to rerecheck everything ^^'). Anyway I think I will upload all the .stl for those who don't use sketchup, and then re-upload them if they change.

watsdesign on Jun 24, 2012 said:

re-uploaded the x-carriage (the holes were not 3,2mm as intended)

Great job!!! Very simple.

Alessio on Jan 18, 2012 said:

looks nice!

what software did you use to design it?

watsdesign on Jan 19, 2012 said:

Thanks !

I used Sketchup, except for the eMaker Huxley parts that were imported from .stl and tweaked a little :)
