Designed this Minimalist x axis tensioner for my ender 3, i made it as small as possible to not have a distracting look when installed on the printer. It tensions using an m3 bolt/nut and an allen key.
A couple notes:
- Since this is smaller and in effect, smaller travel, you may need to trim the stock belt by around 5mm.
- this tensioner uses a GT2 idler as opposed to the stock bearings, its one of the things that enabled this to be small and gives the belts a better path because the stock idlers are larger than traditional gt2 idlers which tend to have alignment problems.
- If you are using a 5mm bore GT2 idler, you will need a 5mm to 3mm adapter in order to fit the assembly(part is included)
- You can substitute the m4 mounting bolts and t nuts for m3 ones if you want.
