I bought a bulldog XL and at first it seemed really well designed, pretty much perfect. Then I found out it wouldn't fit my e3d v6 despite several seller websites claiming it works with e3d hotends. I eventually found a washer that would make it work. I filed down the plastic enough to get the fan bracket onto it and then cable tied it to the z mount of my k8200/3drag. This was enough to print a proper mount. I printed the mount successfully. After days of frustraton and dodgy modifications I almost had everything in working. I went to disassemble the extruder so I could place the new printed mount over the reduction gearbox. I unscrewed one of the two identical end plate bolts with the hex head. The other was on obviously too tight and the allen key rounded off the head the first time I tried to turn it. I hadn't touched it previously. Why the hell is the hex head so small when it doesn't have to be? Now it is stuck in there and the nearly $200 I spent for this extruder is down the drain. This is the latest in a long line of purchases plagued with incompatibility problems and poor design just trying to get this piece of garbage to print. If it were half organized 3D printing would seem to be a giant scam. I am close to throwing the whole thing in the trash. Is there some way I can fix this? I thought about trying to drill it out but the bolt is tiny and there are so many things to ruin in the process.
