Q & A

  1. James Edwards

    Can you do these without the rounded tops that could be used to cut & paste onto other existing tiles (docks, caverns, old dungeons) as well as other brands of 50mm tiles?

    • Matthew Barker

      These do have flat tops, it’s only the trial pack that has the rounded top

  2. marcelino.lopez

    Can be used on a comercial project? (I mean, a dungeon with this system on his tiles)

    • Matt Barker

      Yes the OpenLOCK system is Opensource. You can use these templates to create your own tiles. If you want a commercial licence then we can give you one. Please contact us via the contact page for a commercial OpenLOCK licence

  3. rsimoes (verified owner)

    What version of OpenLOCK is this? It includes a 5.1 clip, but the preview images point to a Thingiverse design of the 4.3 set.

    • Matt Barker

      It’s version OpenLOCK Version 7.1. Its backwards compatible with all previous versions

  4. cryptoscientia (verified owner)

    Do you print the openlock clip as a fully solid object?

    • Matt Barker

      I normally print them at 20% infill, but if you print solid they won’t take long to print and will be stronger

  5. rsimoes (verified owner)

    Any plans for angled tiles so as to create hills and other slopes?

    • Matt Barker

      Yes for sure, we could add them in a future campaign.

  6. gbroome

    How do you get the X or T pieces to work? The clips tend to interfere with one another.

    • Jo Boorer

      The X and T are designed to work in a T section and cross section and have all the clip holes so that you have the option to use the clip direction that works best for you.

    What happen to the file ‘SA-TRP’ it is missing from v8.0 update 4th May 18?


    • Sam Campbell

      Sam Campbell

      The file is called “SA-TRP-v7.5.stl” and is located in the secondary floors folder. You can re-download the files if it’s not appearing for you.

    So what is the Bool Tool and where do you get it from?

    • Sam Campbell

      Sam Campbell

      We’re currently revising the bool tool that was available for the original OpenLOCK system. A bool tool is user for cutting OpenLOCK connections into 3d models using a Boolean operation in a 3d Application.

  9. zen17h (verified owner)

    Any update on a new bool tool release? I’ve got several walls to design and had to ‘cut’ out connector pieces from existing designs, but had a couple off by just a tiny enough bit that it matters

    • Sam Campbell

      Sam Campbell (verified owner)

      We’ll have a new set of bool tools released in the next month or so.
