What?

This is a Z-axis support brace to stiffen up the Z-axis of the Prusa Mini/Mini+.

You want it if you move your printer from time to time, if you raise it using Mini Base mod, if you use Squash Ball Feet System mod, or anything else where you wish to stiffen the Z-axis of your printer.

This is a remix of Prusa Mini Z-axis support brace that is a remix of Prusa Mini Z-axis support that is a remix of Prusa Mini Z-axis brace.

Why?

So, why should you go with this 4th iteration of the support brace?

The main reason is that the Prusa Mini Z-axis support brace remix had several visual issues in the model which resulted in bad visual results and probably worse strength. Here's a preview of it from the top front:

And here's a preview of it from underneath:

You could see on all of the Makes that they had this flaw, and even after multiple reports to the author, the model wasn't fixed.

Being a perfectionist and liking the model, I had to do a remix.

Instead of fixing a broken model (which clearly had lots of other smaller visual issues), I've remodeled it completely from scratch.

The attached 3MF file has all the proper settings, ready to go including:

• Correct placement of the model to ensure minimal support
• Correct placement of the model to ensure minimal visual seam
• Custom seam below the model, so seam isn't visible from the top front view
• Custom organic support (you have to be on PrusaSlicer 2.6.0 or later for it to work, download it at https://github.com/prusa3d/PrusaSlicer/releases)
  

How?

You will need extra bolts and t-nuts. Find the BOM (Bill Of Material), and the assembly instruction here: https://www.printables.com/model/58456-prusa-mini-z-axis-support

The model will fit on Prusa Mini+ (180x180)
