So if you just want some lighting for your dartboard, are not interested in the Autodarts scoring system, and you like our redesigned ring, this is the model for you. Look for print profile: NEW - OMMO LED ring. Assembly details are in the instruction manual PDF.You have two options:Single-colour ring – do not print plates 10, 11, and 12.Dual-colour ring with a nice subtle colour line – do not print plates 4, 5, and 6.6.1.2026 - Some of you have various silencers behind the dartboard, so into the print profile was added two new length for legs, +30mm and +50mm. Can be found in the main print profile: NEW - OMMO Autodarts ring7.12.2025 - complete redesign and release of version 2 Boost MeThank you very much for supporting us by sending boosts. For us, this is also great feedback that shows how satisfied you are with our model :)MembershipIf you are selling 3D-printed models, we offer a commercial licence, which you will receive by joining our membership. You can also join our membership if you simply really like our model and want to support us even more :)As we received a lot of positive feedback on our original design, we decided to sit down again, think about new improvements, and make the whole design even better. So we started completely from scratch. We set three main goals for the new design (and a few extra ones). The must-haves were: no supports at all, an even sturdier ring, and an even cleaner, more pleasant design to look at. FAQ – Frequently Asked QuestionsDo I have to use PLA-CF?No, you don’t have to. You can use any PLA or PETG filament you prefer and have good experience with. We used PLA-CF mainly for aesthetic reasons, as the layer lines are less visible. What LED strip should I use?If you already have good knowledge about LED strips, you can choose any you like. Our only recommendation is regarding light output: we suggest something between 1000–2000 lumens per meter.If you want to know what we used: link Why am I getting warping on some parts?Warping is a common issue in 3D printing, especially with larger parts. It mainly occurs on open printers or when bed adhesion is not ideal.Our recommendations:If you print on an open printer, make sure the room temperature is not too low.Ensure you have good bed adhesion.Use a build plate with better adhesion, such as the Bambu Lab Textured PEI (Supertextured) plate.What camera can I use?So far these cameras are confirmed by us or other users:GXIVISION OV9732, OV2710, IMX179 and same for cameras from HBVCAM.&nbsp;&nbsp;What has changed in the new redesign:no supports at all – even though the previous version needed very little, it was still a pain for some users, especially beginners.a new dual-layer LED ring design – this significantly improves the overall stiffness of the ring. There is also a second benefit for users who prefer to print the model in white filament: the inner ring can be printed in a darker filament to prevent LED light from shining through the ring body. Or you can simply use this approach to customise the overall look of your print.a cleaner design for a better appearance – hidden wall-mounting screws, added optional decoration and colour customisation, and slimmer, more elegant camera mounts.a diffuser for the LED strip – this is optional but recommended. It hides the LED strip, diffuses the light, improves the overall look, and makes the ring even stiffer.a new printable template for mounting the ring on the wall.some improvements in the assembly instructions PDF, based on feedback we received.&nbsp;Explaining the print profiles:The top three print profiles belong to the newly redesigned model (let’s call it version 2). Any profile starting with “OLD” is a print profile for version 1. We will keep the original design in the print profiles for two reasons: first, if existing users lose their downloaded files, they can still re-download them; second, some users may still prefer the first version.The first profile, named “OMMO Autodarts ring”, is the main profile for printing the whole model. It is split across multiple plates (for 256×256 build plates).The print profile named “Customisation” contains the parts used to customise the look of the OMMO Autodarts ring and is mainly for multicolour printing. Changing the colour is very simple, as the coloured parts are created as separate objects in the STL. In your slicer software, search in the objects list for the part named “PAINT ME” and simply change the filament assigned to it.Next, the “Mounting template” is a printable template to help you mount the OMMO Autodarts ring on the wall by marking the holes for screws and cables.Explaining plates from the print profiles:“NEW - OMMO Autodarts ring” print profile. This is the main print profile. You will need to download it in either the single- or dual-colour version.Plates 1, 2, 3, 4 – You must always print these.Plates 5, 6, 7 – Print these only for the single-colour version. They should be skipped if you are printing these parts from “NEW - Customisation”.Plate 8 – Always print this.Plate 9 – Print this only for the single-colour version. It should be skipped if you are printing these parts from “NEW - Customisation”.Plates 10, 11 – Print these only if you want diffusers; they are optional. If you don’t need them, you can skip them.Plate 12 – These are legs extended by 30 mm. Normally you skip this. It’s only for special cases, and if you print it, you must skip plate 1.Plate 13 – These are legs extended by 50 mm. Normally you skip this as well. It’s only for special cases, and if you print it, you must skip plate 1.“NEW - Customisation” print profile. Download this profile if you want the model with coloured lines, as shown in our photos.Plates 1, 2, 3, 4, 5 – You can print all of these plates to achieve the same effect as in our photos. In that case, skip plates 5, 6, and 7 from the “NEW - OMMO Autodarts ring” print profile. You can also mix and match the design according to your preference. For example, if you want only the ring to be dual coloured and not the cameras, print just plates 1, 2, and 3 from “NEW - Customisation”, and print the camera parts from “NEW - OMMO Autodarts ring” (plate 9).Plates 6, 7 – Print these only if you want diffusers; they are optional. If you don’t need them, you can skip them. Also skip these if you already printed the diffusers from the “NEW - OMMO Autodarts ring” profile.Supplies:For printing, we used Bambu Lab filaments – PLA and PETG. The list is provided at the top.Screws and heat-set inserts (Ruthex brand) are from various hardware stores, but we also tried to list usable alternatives from Maker’s Supply, also shown at the top.For the camera version, we went with one of the most popular options: the OV9732 with a 100-degree angle (the rim around the camera PCB has to be cut off to fit). In the print profiles, also check the “camera size test” profile in case you have a different camera model with similar dimensions. This way, you can test if your camera will fit without wasting a lot of PLA. If it doesn’t fit and you have another commonly used camera for Autodarts, contact us and we will check the possibility of adapting our model.&nbsp;Hints and Tips:for Autodarts setup, we cover some basic instructions in the PDF file, but we always recommend visiting the Autodarts creator’s page as well. &nbsp;Version 1 of the OMMO Autodars ring - READ BELOW ONLY IF YOU HAVE OR ARE INTERESTED IN PREVIOUS MODEL:You can choose from 4 variations. Two of them are just for lighting your dartboard, and the other two also include cameras for Autodarts. Each of these two variations has two options: either with 3 legs or 6 legs. We prefer the 6-leg option, even though it requires more PLA, because it makes a significant difference – it’s like a tank :)&nbsp;Assembly variants:&nbsp;For more details, it is important to read the instructions in the PDF. You’ll find everything you need there to assemble the ring. We have also created 4 different print profiles, one for each variation, so you don’t have to worry about how many parts you need to print for your chosen version. Note: if you are not using support material for the interface layer (Version 1 only)Reset all values related to support interface spacing to match the values shown below. These are the settings to use when you are using the same material for the support interface as for the main material: Please check also our darts holders to complete your setup, just go to our profile&nbsp;&nbsp;
