K1 Max Side Braces

# NOTES: 

19/03/25 The incorrect upload of the Top Right stl has now been corrected. Thanks to those who reported the issue. 

23/03/25 Added two stl's to allow for 270 deg hinges - These are untested but modified to fit https://www.printables.com/model/735524-creality-k1-k1-max-door-hinges-geared-print-in-pla/files with a bit of clearance - Slight modification to the hinge may be needed as space is tight on the top and bottom edge. Feel free to use it as a base and remix, or let me know of issues. Printing my be more complicated due to the overhang and the thin top and bottom edges.

This model was inspired by DerrickDarrell and Fatman80 models, but i wanted something with a better join between the sections, to have more than the standard number of fixings and to have a larger brace area, so i started from scratch and came up with this one.

These braces can be fully fixed to the chassis by drilling and tapping extra M3 holes to line up with the holes in the braces, these not only increase the qty of fixing points to help brace the frame, but also hold everything in place so you can remove the side panels without having to remove the braces.

There are also holes to allow access to the gantry mounts.

I am fairly new to printing ABS, and i had a lot of issues with these warping right at the end of the print, not helped by my K1 Max bed not being great and never giving a good first layer so your mileage may vary.

I ended up having to manually add some supports to the overhanging dovetails so that it would get as strong a support as possible to hold it down.

I might have gone a bit overboard with my settings, so feel free to adjust as you see fit, but my settings are below

You will need to have your settings pretty well dialed in, as the tolerances are quite tight.

On the overhanging joints i have made the hole into a sacrificial layer to force the slicer into bridging that section to improve the  print quality. You will need to break through this layer after printing.

Also make sure that you have your shrinkage ratio set correctly for your filament!

Filament: ABS Polymaker Polylite

Layer Height: 0.2mm

Wall Loops: 7

Top and bottom shell thickness: 2mm

Infill: 15%

Infill Pattern: Gyroid

Supports: Snug

Support Pattern: Rectilinear

Support Z Distance Top/Bottom:0.1

Support Interface Spacing: 0.25

Brim: 10mm (Outer only)

Fixings:

M3 x 12mm - Extra fixings for brace to the chassis

M3 x 20mm - Fixings for the standard cover through the brace and into the chassis

1mm x 5mm foam tape, to add a seal/damper to the mounting surface of the standard panel

NOTE: Although i added a new hole to the bottom corners, i did not use them as there are some fixings there, but they are self tappers as they go in to plastic, and i didnt have any appropriate length fixings, but they are are there if you want them.
