People have seen the front of their HBP sag almost 2mm after 30 minutes. Before this modification I was getting 1.8mm sag after 30 minutes and now .45mm sag after 30 minutes.
If you don't have access to a laser cutter let me know and we can work something out.
It's a simple fix. It's just some additional support without adding a lot of weight.
You will need 6 M3 16mm bolts & nuts. Disassemble and replace the main plate. I've included the two back plates and the front plate because I found the orginial files were not the same as the shipping model of the Replicator so I updated them to match and I modified the back to be more Replicator2 styled. Just cut it all out on a laser cutter with 5mm plywood.
I also added a center hole up front so if you want to modify your HBP to 3 point its ready to go.
If you want one of these in a kit form let me know I can do it for $25 which includes shipping if you're in the USA.
