3 different Prusa MK4 Z axis dust covers :)

Hello everyone :)

There are already many different solutions to prevent dust or small plastic parts from falling into the hole in the Z-engine. Unfortunately, none of them appealed to me so far, so I developed my own solution. While my first design was being printed, I went to the gym and came up with two more possible solutions, which I quickly constructed straight afterwards.

So just choose one of the solutions :D They all have their advantages and disadvantages!

- MK4 Dust Cover : Super stable. Can have too small tolerances with a crooked threaded rod, though. - MK4 Dust Puzzle : Quick and easy to assemble. But can come off if you juggle your printers. - MK4 Dust Clip : Holds juggling but can only be mounted overhead with two right hands. If you choose the Dust Cover (as I did) here is the assembling instruction.

- Print the parts and clip the rear part into place. 2. Moove the Z motors a little around and veryfy that the dust cover does not touch the thread.

3) Install the second half of the dust cover and moove the Z motors again.

Ideally, none of the dust guards should touch the thread of the Z-axe.

Material: I recommend using PETG as with the rest of the printer to avoid warping due to heat. Especially of used inside an enclosure.

Have fun and keep printin!
