NOTE: after printing i noticed that the hole positions are slightly off, you will need to cut off one of the 'arms' to mount it on a Makibox printer, if you are modifying it for your printer, this shouldn't be an issue This is a quick warning sign i made for my makibox 3d printer, it it designed to be held in by the front screws, i have included the scad and dxf's so that it can be modified for other printers, if you modify it, please upload it and attribute it to help out others
