This is a replacement plate for the Simax3D Iron M1, which replaces the stock hotend assembly with an E3D V6 mount.
I designed this because the stock hotend assembly is insanely loud. You will need to sort out a part cooler. I'm using a really nice one that runs off a 5015 blower; you can get that here: https://www.thingiverse.com/thing:2469775 You can reuse the 5015 from the stock hotend assembly. You do want to get a high quality 24V hotend cooler, as the original stock fans are really bad.
I printed mine in PLA+, though PETG or ABS would be better. I used 50% infill, and I'm a dozen prints in on this setup, and no drooping, or other issues. Bed leveling has held solidly.
Do install the silicon boot on your heater block, and secure it with some kapton tape. I found that cooler was too efficient, and the hotend was struggling to maintain PETG temps.
