Extruder Mounting Bracket - Makergear M2 3D Printer

thingiverse

This design is almost identical to the stock R3 version available here: https://github.com/MakerGear/M2/tree/master/Printed%20Parts/STL The main difference between this and the original is that I removed the beveled edges on the flat bed side. With PETG, these edges can cause small parts to detach from the printing platform more easily. Apart from that, the design remains the same as the stock version. If you're using PETG, consider adding a 2mm attached brim around your part to prevent it from warping and detaching from the bed while printing. I use 250C hotend temperature, 50C bed temperature, and Buildtak on my printer's bed top surface - it works like a charm. The mount on my printer snapped where the screwdriver hole goes through the clamping arm, but that was because I had the weaker R2 version installed. The R3 design seems to have been created to address this issue, as it has no screwdriver hole and features a thick band around its middle section for added strength. It's worth noting that the stock part was printed with 20% infill - I highly recommend printing at 100% infill for critical parts like this one.
