    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?

    • Avatar

      Matthew Barker

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

    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

    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

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

    • Avatar

      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

    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.

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

    • Avatar

      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.

      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.

    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.

    Any word on the bool tools? Last update was January 2019.

      We’re looking at doing an update after we release the roof templates soon.

    HI Sam – Just wondering if you can provide an update on the bool tools? Thanks!

      Nicholas Jebson

      Hey Shawn, Sam is working on an update to the tessellation template as we have a couple of new OpenLOCK shapes to add, and we are planning on adding in the bool tools with that update. We are expecting to have it done during the next Kickstarter.

    Hello, would it be possible to have 3 ″ high walls for games workshop games, 2″ walls (especially with a floor below) do not allow you to fit a minifigure below, you also use 4″ for buildings such as cathedrals (which are not present either) for which the 4″ perfectly render the effect of magnitude but 3″ remains the most suitable for standard buildings.

    • Sam Campbell

      Sam Campbell (verified owner)

      3″ and 4″ walls are just the same base with taller walls. The only important thing to take in account with the tessellation templates is the floor ports and the side wall ports. These can be replicated upwards if you wish to extrapolate to a taller wall set.

    Do drawings with dimensions and annotations exist for the assets in the Tessellation Template package?
