Hi to all. I want to share with you some STL files that I just uploaded to Thingverse.

I always liked OpenLock system and ability to create modular terrain. But the problem is – I am 15mm gamer, and OpenLock is designed for 28mm scale.

So I remade classical OpenLock for 15mm.

The new system uses the classical OpenLock clip, but have different grid size.

Because there is no standard in 15mm basing, some people use US/UK pennies or Eurocents, while other use washers.

Because of that I decided to use 20mm squares so Players from UK, US and EU can use these tiles.

I have no idea what you're talking about, but it sounds like a lot of work, and that it will be useful to others. Kudos to you!

Thanks for doing this!

I have no idea what you're talking about…

The last piece is the clip; it inserts in-between pieces to hold them together.

Yes. Its a system to create modular terrain. I remade the frames. Soon I will upload some more stuff.

SirFjodin, this is great!
Have you talked to Printable Scenery, the people who created OpenLock? Maybe this is something that can be promoted for 15mm gamers? The xxxLock standards are all very 28mm-centric right now.

I have no idea what you're talking about

OpenLock is a public standard for 3D printed modular terrain. A standard-sized clip is used to connect together different pieces. The theory is that no matter the creator of the terrain, as long as they adhere to the standard, their terrain pieces can fit together and be used together, subject to genre, theme, and design, of course.

Thanx gregmita2. I haven't yet talked to them :) But ot seems like its a great idea.

by the way, the thickness of the parts and size of OpenLock clip is absolutely the same, so its kind of compatible with 28mm one.

It just use 20mm grid instead of 1 inch one. Because most people who play skirmish games with individually based figures, base their 15mm minis on less than 20cm bases.

Here are some measurements I have found before modification of OpenLock:

Australian 5 cent – 19.41 millimetres
US Cent – 19.05 mm
Euro Cent – 16.25 mm

UK penny – 20.3 mm – and its a bit bigger than 2cm. Thats why I think walls need to be at least 1mm thinner than 1cm (around 9cm) so UK players may use the tiles.

I also find that in UK youy can use M8 (15mmØ) and M10 (20mmØ) washers. And Brigade Models movement trays are designed for them

As for me. I live in Australia and use 17mm Washers.

Here is Work in Progress on 12x12 square tile.

It's made from 4 6x6 tiles, connected with Open Lock Clips.

I have a lot of open forge tiles (very similar to openlock) I have printed and magnetized, which I am using for 28mm role playing gaming, but the ones I have for 28mm would work really good for 15mm also. I wargame in 15m and have hundreds or 15mm fantasy minatures painted. I base my 15mm mostly on 5/8mm washers but some smaller miniatures like goblins sometimes go on size 10 washers which are 1/2".

I printed my tiles at at standard size based on inches, but if I had to do it over, I would probably make each square to be something between 1 1/8 to 1 1/4 inches. I find miniature bases make for tight fit and extra size on the tile would be much better.

If I decided to roleplay in 15mm ( my kids are mostly who I play with) I would use my tiles printed( sized for 28mm and would be much happier.

My suggestion is to print for 28mm, use short walls and then just print some tiles that are square wide instead of having everything 2 squares wide.

The only issue I have with square wide tiles is they cant be easily magnetized and I would have to use clips which really sucks after you have used magnetized tiles.

The open forge tiles have the walls the tile its self, which would be great for 15mm miniatures anyway. I do have some narrow hallways with walls printed ( self designed) (which is a 2inch wide tile but with only a 1 inch wide hall) which would solve the issue of no magnets. but really magnets are the key to enjoying tiles ( at double the cost, as the price of magnets adds up quickly) is to magnetize them. Also, you never know when you will decide to use 28mm anyways, and if you make your small, then your kind of out of luck, but tiles for 28mm can be a great thing even for 15mm
