Troublemaker 3D printer (Ultimaker derivative) by Musti Mar 5, 2014


Troublemaker is a derivative from the highly popular open-source 3D printer Ultimaker Original by active individuals of Drustvo Elektronikov Slovenije (hobby electronics society) designed for the members group 3D printer build lead by myself. With about 80 members very interested in having a 3D printer, we have incorporated modifications and improvements into a derivative design nicknamed Troublemaker.
The main differences from Ultimaker original are:

  • Improved enclosure design, allowing for easy heated chamber upgrade. The enclosure has been enlarged to house the bowden above print head, so only flat plexy pieces are needed to enclose it.
  • Added support to mount two extruders and reels for dual-print configuration.
  • Can support almost any printhead with a 3D printer mount, the main choice is E3D metal-only hotend, which performs very well with PLA and ABS. The use of EasyE3DMount design is suggested to mount it, the new version has magnetic mounted cooling fan for easy swapping of different fan duct designs and removing it.
  • Uses 3D printer electronics available at PlanetCNC, that is directly mounted into the front panel.
  • The design includes mostly widely available parts.
  • Belts and pulleys proposed for use are GT2, with PlanetCNC 3D printer carriage design, open belts can be used.
  • The print bead has been modified to use 3-point levelling and its sturdiness increased, however higher precision laser cutting is required for it.
  • PlanetCNC Extruder design uses a NEMA 17 stepper with planetary reductor, a more compact design compared to the original one.
  • Enclosure includes mounting holes for motor belt tensioner modification, Z switch adjustment modification.
  • Bottom side mounting holes for power supplies, stepper drivers.
  • Enclosure mounted mains IEC socket with a built in fuse and switch.
  • Mounting holes for cables.
  • Printers are fully stackable
    The documentation includes:
  • Bill of materials
  • Assembly instructions (Slovenian language only for now)
  • Laser cut drawings
    Power supply socket JR-101-1-FRSG-02


This printer is easy to construct once you have all the right parts. Sourcing them should be easy as they are all chosen to be available. Check your local 3D printer shops and online. The Bill of materials included in the files lists all the necessary parts.

Hey very nice design and instructions :) i made the chassis yesterday, and am so excited about getting it running, there are a couple of things i am wondering about and that is the "bone shape" piece is that for axis alignments ? and what is the reasons that you went with the PoStep25-32 ? and could i get you to upload the CAD files ?

Can I possibly order the panels for this from someone, or do I need to redirect my efforts towards my my laser-cutter project?

Hello! Congrats for the Great design! Whats the Size of the print area? And do you guys have the dual e3d design ready for this machine?

Print area is 20x20x20, same as Ultimaker Origina. Everything is ready for dual extrusion, use the head mount like this: http://www.thingiverse.com/thing:159390

The Butterfly: lightweight and easy head mount for LM6UU crossbars (eg. Ultimaker)


Hi, excellent work, I really like it! But... could you add the two missing references to my CC-BY designs in the margin ? And I would have find this UM derivative sooner with them! ;)
You may want to check my own wishlist here, by the way http://www.tridimake.com/2014/01/features-and-improvements-for-a-homemade-ultimaker.htmlhttp://www.tridimake.com/2014/...

Yes and this is why I like your printer :)

Thanks for the notice, I completely forgot adding the assembly parts in the sources. Fixed now. You have some very interesting reading on your website. My use case for these printers is designing a wireless optical communication system http://www.koruza.nethttp://www.koruza.net

Thanks again for the links, I am lazy like many people.. it is much easier to check what interesting parts you gathered for your printer :) Do you have some changes you would do, now that you have used it for some time?

To be honest, I am extremely pleased with it and would not change much after running several of these printers for 1000h+. The only thing for improvement would be to reinforce the Z-stage s it deforms slightly due to heating and add an auto-leveling bed. Mechanical in nature, so the nozzle presses it down until it clicks into palce in 3 corners. Pure mechanical auto-leveling. There was a project for this once somewhere.

I got my copy of .dxf files from there.

Unfortunately there are no instructions in english, photos should be sufficient. Feel free to translate instructions to English.

Just starting out. I liked the design of this. Are there instructions in English? Pictures are great though.

Nice work! Very well documented. Hats off!

All the drawing are in DWG format, which cannot be opened in Open Source software such as Inkscape. Is it possible to upload these in DXF format? (Or SVG)?

Ditto, I am thinking of making a couple of these for our high school but I don't have anything that will open .dwg. I really like the features you have come up with in this.


If you follow the link to the website with originally posted sources: http://www2.drustvo-elektronikov.si/?p=1030 there are dxf, dwg and pdf. I am uploading them there as well not to cause any more confusion.

Ugh.. Sorry I missed that and thanks. I am hoping to build (eventually) four of these for a couple local schools. I'm putting the plan together now then I'll build one for the parents to see and help fundraise for the others. Thanks again.
