The original model was already optimized i just changed it a little cuz i was bored

also changed the threaded inserts for nuts on bed mount

printed in:

• Gyroid infill 40%
• 3 perimeter
• No support
• PET-G
• Dynamic layer height - saves a lot of time

well let me explain why is this more optimize maybe it will help someone

The size

Change this size because it made no sense why is the right side so much wider than left side so a removed some of it also at the top to match

Tears

well not actually

These teary-shaped holes are actually made for better support, or should I say no support because they require none

want to understand why? watch this

Nuts

why I added them, mainly because I don't have M5 inserts and, secondly, because they are not needed. When disassembling the bed, you will be left with rollers, M5 27mm screws, M5 nuts, and a spacer. So if you already have the nuts left, why not use them?

Why is there only space for half a nut? Because when you tighten up the screw, it will act as full space, and also because it looks cooler (which will probably create some problems when assembling, but naaa).

update: turns out this worked but i still changed it to full size nut so i could add some more height to the screw

Fillets

Why did i add them?  No, not because it looks cooler, but because it actually print faster in this orientation. Think about it: when you print a squere, the nozzle will have to stop completely on every edge before continuing printing, but on a circle, that problem doesn't exist; it just prints at a constant speed. And also because it looks cooler + less material used.

More fillets

I added fillet here to gain more strength and to faster print.

also here

Chamfer

I also added a chamfer to this hole so the bearings would go in easier.

i added chamfer here also so it wont need support to print, because it will build up on good angle 

Lastly

let me just say that the main model was not bad at all the author focused on bringing the idea to life and i am thankful for that and he actually had a good design in mind for example this

This is actually implemented for printing without support. It allows the nozzle to print overhangs that are connected to the other side so they will not change shape due to gravity. This is a genius implementation and it is called sequential bridging technique. Here is a video explaining it better.
