This is a simple belt tensioner for the classic Rostock 3D Printer and its derivatives like the Rostock Mini.
It was simply derived by removing some mass from the stock idler end STL (credit to Johann Rocholl for the design!), so you can easily "slot-on" it to the rods. Great for removing belt slack.
Additional items:
M8 x 50mm Hex Bolt: 1
M8 Hex nut: 1
608zz bearings: 2
You can take it a step further by using the flanged F608ZZ to contain the belt and a nyloc nut, but so far the standard parts have worked.
