OpenBuild's Mini V-Rail 2020/2040 Extrusion Mount Plate

thingiverse

I was determined to maintain the length of my Openbuild's Mini V-Rail, but I couldn't find any other plates/parts that would be simple enough to use without modification. So what did I do? I decided to fabricate my own part in Solidworks and came up with this design. The plate's (all three of them) are 10mm thick, with 3mm cut out for the screws to sit in such a way that it doesn't affect the extrusion's, which leaves 7mm. For hardware, I would suggest a 10mm M5 screw, which will work perfectly for the Mini-V Plate as well as being used with the T-nuts to secure the extrusion to the plates. At 60% infill and five outer layers, the parts are super solid, even in PLA. I don't think I would be able to break them unless I literally took a pair of pliers and a vise and snapped the top part off for the Mini_V_Extrusion_Mount_Side and Mini_V_Extrusion_Mount_Side_Chamfer designs, which I wouldn't do. Anyways, all three parts work great on the OpenBuild's Mini-V Plate and will mount either a 2020 V-Rail or a 2040 V-Rail Extrusion. Maybe even a 2060 if you used the flat plate and mounted to the center Rail, but that might be pushing it. For the mounting holes, they are made to be used with five-millimeter screws (it doesn't matter if they're cap or hex head), but the low-profile screws from OpenBuild sit practically flush with about one millimeter of spare room on all the holes. If there's interest in these plates, I would possibly be willing to make more of them to facilitate all sizes of the OpenBuild Extrusions so that other people can use more than just a 2020 or 2040 extrusions. Just print them as they are downloaded. YMMV on supports as to how good your printer does rounded holes. If it doesn't like doing a smaller hole sitting on top of a bigger hole, then possibly enable supports for that one little section of the print. It's only a nine-millimeter hole with three millimeters of height before the five-millimeter hole takes over. These designs are not to be sold by unauthorized individuals or used in an industrial setting unless person/company has contacted me and we can work out a proposition.
