Mini V Gantry precision belt holder

thingiverse

I like the "[Anet A8/AM8 2020 X-Axis](https://www.thingiverse.com/thing:2439194)" conversion design by *thaug29* and generally speaking I like the Mini V Gantry Set on V-slot extrusion profile (wether it's 2020 or 2040) with the belt being inside the slot, it's super stiff, easy ton install, pretty cheap, lightweight, and super accurate, BUT there's something I don't like about it. The belt is attached to the gantry plate that slides a few millimeters away from the profile, meaning that the closer you get to the pulley, the more angle the belt has, eventually rubbing against the printed part that holds the 2020 profile and reducing the print precision (see 3rd attached image). I came out with a simple yet efficient design to force the belt straight into the slot. Instead of attaching the belt to the metal plate you just insert that plate between the Mini V Gantry plate and your carriage, make a loop around the plastic and hold it with a zip tie using the provided holes (see picture). That's it! :) *Be careful tho as this belt holder will only be usefull to you if you're using a design where the belt is running INSIDE the extrusion's slot like on my pictures and in the mod I linked above.* The plate is only 3mm thick so you will still be able to use the standard 10mm bolts to bolt your carriage. It will also allow make the belt installation easier without having to disassemble the carriage. *PS: sorry for the pictures' quality, my smartphone is crap!*
