Ive gone over the model multiple times, i cant see anything else i might need to adjust. They have predicted another heatwave over the rest of the week and weekend, So i wanna get this printing done before that hits.
I added a chamfer to the mount holes for the encoder / knobs, Not that it would ever be visible. Oh i modified the main edge fillet on the frame too, i changed the tangent value, which looks like it might print better, but i have my doubts.
Something i have noticed on the version that finished printing earlier is that the radius on the edges of the frame dont feel very... radiussy.. I dont know the word for it. But it feels more like a rounded chamfer than a true radius. Not sure why, but hopefully the adjustment i made will change that for the better. Guess ill find out later🤷♂️
It annoys me how thick it is. Its only that thick because of the batteries😐
I fucked up the back cover posts on the frame side 😑
I made the posts 3mm shy of the top of the back of the frame, and the back is 3mm, which means the screws would have been poking out the back. I should have made them 4mm shorter to allow room for the screw heads 😭
So now i have to decide if i wanna reprint the entire frame just to have shorter posts.
I know it will annoy me if i dont do it. But i dont wanna print it and then realize i need to make another adjustment. I dont think there is anything else... but i know i wont realize there is until the print is almost finished 💀
Im working on the back cover of the LED-A-Sketch and considering adding a kickstand. Im gonna try and sand and polish the print to see how it comes up. But in doing that, its gonna be a bitch to sand anything that's intricate, which a built in kickstand would be.
So im now thinking of just leaving the back as empty as possible, and design / print a seperate kickstand. 🤷♂️
A problem im having with the frame is that the radius on the "face" of the frame is kinda big, originally its 5mm. Im not sure what the radii is on a real etch a sketch, but at 5mm its causing issues with the prints, the overhang is just a little too much, I dont want to use supports cause the scarring would look worse than a shitty overhang.
The print has finished, The surface quality is way better, but i might reduce the radius of the fillet on the outside of the frame, there is some quality issues with the overhang.
Im not really a fan of the smooth texture on the front of the frame, but i wasn't a fan of the texture from my original build plate either.
The new buildplate i have is double sided, and it has a different pattern, so i might try that on a test object and see how it looks, but it looks like a strong pattern so im not sure.
Im re printing the frame, its gonna take like 3 hours, but hopefully the slower speed will help improve the surface finish. 🤷♂️
I was just making sure everything would fit the height of the frame, and it seems i forgot to allow for the spacer / diffuser, so i have to increase the thickness of the frame by 8mm. Which sucks, cause the current thickness feels / looks good when compared with the original.
The batteries are the tallest thing in the case, so if you was never gonna use it portably, it could be much thinner.
Test fit, it looks pretty good i think. I wanna reprint with the smooth print bed, im not a fan of the texture. Also, the knobs arnt actually installed, they are just shown to see what they look like.
I need to adjust the knob, the depth of the hole for the rotary encoder is a little deep and makes the top of the knob a little translucent.
I haven't shown you the sides of the main red "frame"... because they look like shit. Not sure why.🤷♂️
Diffuser is done, hopefully it looks good.
I got some plastic polish kit from amazon for that phone i brought.
I was just cooking something and hovering around in the living room, I decided to look out the window, and saw a car go past staring at our house, so i stepped to the side and kept watching whilt trying to hide, and the car pulled up, the dude was looking out his back window and made direct eye contact with me. I just moved away quickly. Then a few seconds later... the door knocked, then again, so i go and answer it, Its my amazon delivery i forgot about😂😭
Amazing what a difference a slight adjustment of the z-offset can do for a first layer.
The top is 0.03mm z-offset, the bottom is 0.07mm. There is still some ripples in the bottom one, but its really hard to see, im just printing another with the z-offset at 0.08mm to see i f that clears the remaining ripples.
Third of the way through the print and its still looking good. So hopefully that fixed it.
I have no idea why, but that print had really bad stringing. i just did a stringing / retraction test and it printed fine... So im gonna try printing it again with scarf joints and a slightly higher retraction length. Hopefully it finishes without issue😒
Printing the LED spacer in black. I added a slight chamfer to the top surface to try and make the separation lines a little thinner. Im not sure it if will work, but if not, i can just flip the spacer over.
I will never understand why printers print in the order they do.
You would think, with a grid, you would just start in one corner and work your way across, row by row. But nope, look at this
What kinda logic is that😂
I just printed a test diffuser with multiple thicknesses to see what works best.
Im not sure why, but the slicer refused to print the 0.55 and 0.65 layers as separate thicknesses, it just printed one large 0.55 layer.
I dont understand why, but the 0.4 section looks thicker than the 0.45mm section?
I prefer the 0.45 section, but i think its personal preference, i like all of them, but 0.45 looks best to me.
I will reprint the led spacer tomorrow in black, and ive ordered a smooth pei print bed to see if that would make a better diffuse surface.
I just test fit the pcb into the frame of the led-a-sketch, it fits perfectly, but the little clamps on the back need to sit a bit closer to the pcb, there is a little too much wiggle room.
Im not too happy with the print quality tbh, I need to fiddle with the settings, and i turned scarf seams so i might try without it next time. Next time i print the frame, im gonna print it with the front side of the frame facing upwards, it would need supports, but it would let me do ironing on it to smooth it out, and it wont have the pattern of the print bed embossed into it.
The holes for the pots turned out pretty good considering there wasnt any support lol.
The grid thing covering the leds, i dont know what its called, so i just call it a spacer. i printed it in white originally, but it bleeds far to much light, so im going to try it in black next. I have tapered off the top of the spacer grid, just to try and make the lines a little less noticeable when the diffuser is on.
About the diffuser, i really dont know what to do about it. I feel as tho i could just print a test piece with stepped extrusion heights to see which looks best, I could also just buy a diffuser from ebay or something. I think im going to try the printed one, but i might have to get a new print bed with less pattern on it.
I haven't tested the potentiometer mounts yet
Here are some pictures.
The print hasn't finished yet, but i was just looking at the model and realized i didn't put the little notch in for the potentiometer sticky up metal part to stop it spinning in its hole.
Ill add them now, just incase i print it again.
This isnt what i wanna do with the phone, but can you imagine having it hooked up to alexa? u pick the handset up, it unmutes the mic, u then say alexa blah blah, and you can hear its response via the handset.
It makes the dialing kinda useless, but i was just day dreaming and thought of that 😂
Just ate an edible, now watching Mr Bean Rides Again.
