Lens DOF (Depth of Field) Adapter Rings set & Threaded Adapters

thingiverse

!!!! WARNING!!!! This is a quick but well-working solution for lens mounting and macro photography. Threads work seamlessly with standard 52mm, 42mm, 37mm accessories, lenses, and spacers without any issues. Despite the fact that (three rings set with bayonet fittings can be purchased on eBay for $5) don't trust plastic for expensive or heavy lenses - you do it at your own risk!!!! It's a set of rings I designed as a replacement for BeastGrip's DOF adapter. The main body is 60mm ID and 62.6 OD with three main rings: 36mm, 20mm, 12mm plus adapters for 42mm to 60mm, 60mm to 52mm, 52mm to 37mm, and a 12mm 37mm spacer. Not all of these are necessary for the adapter, but I designed them anyway. The threads for 60mm, 52mm, and 42mm have been tested and work amazingly well with a tight fit on each other and components. The 37mm rings haven't been tested for accuracy yet; I'll come back to confirm or correct once they're tested. Missing from the set is the internal focus screen holder - it will be uploaded as soon as I make some modifications. For the first time, you need to clean all the female thread starts (the bottom sides when printed) with a knife to remove any excess plastic at a 45-degree angle so you won't damage the inner threads. Be patient on your first attempt at putting them together - it takes time and requires screwing and unscrewing a bit before tightening further each time until it's all screwed in. The rings are strong enough and can hold heavier lenses (such as my helios m44) although, as I mentioned earlier, you're using it at your own risk. I hope this will be useful for you!!! Print Settings Printer: i3prusa Rafts: Doesn't Matter Supports: Yes Resolution: 0.15 Infill: 30% Notes: If your printer is calibrated correctly, you won't encounter any issues. Support is necessary, especially for the adapter with different threads - I used them on all pieces for a clean edge. A little knife cleaning job on the internal edges that face the heatbed will be needed at a 45-degree angle to avoid damaging the threads, and also on the external side. Printed with PLA using a 210 nozzle and 60°C heatbed.
