anet a8 2020 Bowden Extruder adapter

thingiverse

###well here's the story with this.### I wanted to use the L3K extruder with my A8, but the Bowden Remix uploaded is made for 2020 (as well as 2040) frames, so what's a guy to do if all he has an A8 with the stock acrylic frame? I had three choices: modify my A8 into the AM8, modify the files with an Anet A8 mount, or make a 2020 compatible mount for the A8. I went with the 2020 compatible mount because it will be usable with other 2020 extruders as well as extruders that want you to drill your frame. I chose to use a 2040 because the extruder I wanted to use would not mount to a 2020 due to the Anet A8 frame interfering with motor placement. It may not look pretty, but it works. ###why separate parts### Mainly so I could eliminate supports (or at least minimize them). If I only posted an assembled version then the 2040 would require supports, and what if a user wants to use actual 2040 aluminum extrusion instead of a printed one? ###**about the license:**### The no derivatives apply only to modifying the files. Which I do not want. As long as you don't modify the files, you may use them in other things, but note the same license or stricter must apply (meaning "Creative Commons, Attribution, Non-Commercial, No Derivatives" without modifications). This license does not apply to T-Slot nut which has a public domain dedication (CC-0). ###changelog### Base V1 had the wrong layout for the 2020, replaced with V2. Base V2 had screw head holes on the bottom slightly too shallow for screws to fit without using a nut to force it in, requiring three walls and higher than normal infill. Replaced with V3. Base V3 increases the hole depth for the screw head by .25 mm (now 2.25 mm), allowing a screw to fit without needing a nut to force fit it. Screw holes are designed to be tight so it still needs to be press fit that way, but nothing that will compromise the integrity of the part.
