Update 5/31/2019: Printed and tested. It works fine. Added v2 of the purge bucket. I moved it in closer to the mount by halfway merging the legs, and also made them pretty with some hawt fillets. I have such little space between the nozzle and bed that I need that extra bit, but for most setups you're probably perfectly fine with v1. WIP status removed.
Update 5/29/2019: Shortened the legs to make it easier to remove and made the bucket narrower. I placed it into an assembly of the BLV mod and found it was too wide. Since I've seen the entire assembly of everything, I don't think anything should stop this from being fully working! As always, I have provided to Solidworks files to modify it to your needs.
This is a purge bucket, specifically for the AM8 BLV mgn12 mod. It should work on the original AM8 as well, or any 2040 extrusion-based printer.. I have my starting gcode to purge a bit of filament at the home position, which would then just stick to the side of the bed once it moves into print position. That method works fine, but I would usually pull that strand off as soon as the print started.
I designed it all in Solidworks and fitted the assembly together to make sure it... fits.. My setup is such that I only have 2mm between the nozzle and the bed when X=0. I plan on mounting this to the inside extrusion on my Y axis. I have posted all CAD files so if you like it, go ham. If it's too narrow for your build, let me know or extend it yourself.
It is a chamfered and filleted mess, with crazy tolerances. I wanted to make sure it slides out easily, and was therefore not permanently mounted. Feedback welcome and appreciated. The overall height should be 39mm, so it should fit nicely on the side of your 2040 extrusion and not cause obstruction.
