For this week's assignment, I searched for 3d printed pen holders but I needed it with more functions than just holding pens so I was Inspired by this design but it had to be smaller to fit the time and weight so I redesigned it.

First, I sketched a rectangle on top plane then extruded it then using construct I made an offset plane and used it to sketch a smaller rectangle. After that I selected loft from create section then selected the top face of extrusion and the sketch at the offset plane to make the loft.
I sketched on the angled side the slots I needed but first I searched for the dimensions of usb and memory cards and made the slots 1mm bigger to fit in and I'll see if it works after fabrication. After finishing sketch I extruded it.
This is the angled front side with 1 slot for SD card, 3 slots for flash disks, and 6 slots for memory cards. ^^
This is the top plane sketch for holding 3 pens and fit big ones in diameter. I sketched 3 circles and extruded cut it deep in the holder. --->
I made a section analysis from inspect section to make sure that everything will be fine but it needed some changes
This was the last section analysis after the chamfers and fillets and lots of changes in the design to fit the time which was the challenge that truly faced me.
To save the file as stl I right clicked on body 1 to the left then selected save as mesh then stl ( binary ).

After that I opened it using Cura:
1- the machine is prusa i3 mk3
2- filament is PLA
3- I set the layer height to 0.3 mm to reduce the time
4- the infill is 20%
5- the supports I made are touching buildplate only
6- design dimensions is 44 x 50 x 24.5 mm
7- part weight is 20 g and it would take 1h 28mins
8- the temperature of the nozzle is 215C

1-I had a challenge when I first finished the design and exported it to cura I was chocked that the estimated time was more than 3 hours.
I overcomed this problem in design by making chamfers in the corners and extrude down the top face which gave me more space to hold other small things in.
also to reduce the time I increased the layer height to .3 mm in cura.
2- The other challenge was that the slots needed supports and turned red on cura.
So, I went back in time to my second sketch in the offset plane and reduced the width of the rectangle from 35 to 30 mm so the angle became 45 and the supports aren't needed any more ^_^.
3- Last problem was that the slots crossed each other at some points. And it was solved when I changed the angle without having to change the length of the slots.
Last problem after fabrication
Last problem after fabrication
the sd card adapter didn't fit well in it's slot. It needed the slot to be thicker.
So, I could solve it in the design and make it 3mm instead of 2 mm.
Or, I could widen it using tools in the lab after fabrication.

I could imagine 3D parts more and how to build slots with minimum supports
WOW!
WOW!
What is the coolest thing that you've learned this week? What is something that you will never forget from this week?
