Prusa MINI - Z-Bottom + Cover for Heatsinks

Buddy Board Casing RC2.0 - 7 July 2022
Uploaded the buddy for Prusa MINI Clones and the Original MINI Hardware.
Added more rigidity to the front part. A bigger bar with 2 screws instead of 1 for better alignment too… Added an extra square M3 nut on the bottom so you can secure/screw down the stand to the buddy board casing.

For the stands, you only need to print the prusa-mini-z-stand_rc-2.0.stl if you already have the 3 smaller ones.

Hardware Needed (on top of the previous versions, see bottom of description):
M3 Square Nut
2x M3 Screws
1x M4 Square Nut or T-Nut for the 3030 extrusions.

Stands RC1.5 - 16 Februari 2021
Updated the big stand for the Prusa MINI, added a slot for the Y motor cable si it doesn't need to run from the outside.

Stands RC1.0 - 26 Januari 2021
Updated the stands so you do not need support anymore, it was an initial design to use thiccccccc rubber pads as inserts. now you can the stands/feet print without support or if you want the texture of the powder-coated pei sheet you can print it on its side without support.

Release Candidate 1.5 - 15 January 2021
Updated some sections to the model so it's stronger when you screw the casing on the extrusion profiles. The 2 screw holes will now print solid. (see slicer image).
Als added a hole for the Y-Motor Cable so it wont be on the back-outside.
This was introduced with the latest Prusa MINI+

Release Candidate 1

I wanted to put the Prusa MINI on the stands but quickly noticed the whole Z beam will bend away from the printer (to the right if you look at the printer). So I increased the stand so it will support the buddy board case too.

I also noticed the stepper drivers on the buddy board get pretty hot, ok I'm sure they tested the thermal limited BUT electronics don't like to be hot in the first place... So...

During the design of the Z-Bottom Stand, I noticed there was room for those small heatsinks! so I made square holes in the buddy board casing and... now you got something cool!

The bigger stand that supports the Z-Bottom has a channel for the LCD ribbon cable.

Hardware Needed:

4x Heatsinks Size: 0.9×0.9×1.2cm/0.35×0.35×0.47in
