3D-Printed Objects

[joshc]

Thanks to @jessenator there is now a modified 3D model of the Mac II stands which I have ordered a set of to test. Printing larger models starts to get expensive so hopefully they work OK.

These finally arrived today and I think it's safe to say they work!

They definitely seem strong enough and sizing wise they seem pretty much spot on. I don't know how well they'll do over time but my Mac IIfx is fully loaded with 6 NuBus cards and two floppy drives so it is pretty heavy.

Some quick crappy photos to show what it looks like...






With permission from @jessenator I guess it would now be safe to release the modified CAD file that was used to print these.

Fabulous! You have some classic naval architecture going on there in your filleting of the frame:



Quite elegant, got a pic to post for comparison? Thanks for bringing these to life.

Credit must go to @joethezombie for creating the original model and @jessenator for modifying it (adding more structural integrity). All I did was spend money to try it out.

Some more photos

Thank you! I'm by no means an engineer, but I do appreciate the compliment

Here are the two side-by-side

Here are the two overlaid (original in dark teal):

So it's hair taller (probably not noticeable), but I wanted some of the thicknesses to be bolstered.

I'm glad they worked! Sure, I'll attach the rev1 of the design. As joshc and I've already discussed privately, I'll iterate again, publicly, I don't hold any liability for these.

Fab job of jack leg engineering. I like to point out the parallels in Naval Architecture and such. Hopefully this one is better placed and clearly on topic. Last time I got ModSmacked for making a suggestion ahead of time in the middle of a thread for printing something. Maybe I can get that one started again too in this thread. There are at least two more teams who might be interested in development, one's open source I think.

Add a little tab to the baseplate of the model:
Model provided for development/testing purposes only.
User assumes all liability for use and responsibility to provide constructive feedback.

Verbiage may vary with reference to git/not licensing or what not, but user required to trim away notice, before or after printing.

If this doesn't work out in plastic, I can knock together what I've noodled out for a pretty laminated wood version. Not Aluminum Extrusion Slick from the IIfx era, but Mid-Century Modern has its own elegance.

making a suggestion ahead of time in the middle of a thread for printing something.

I'd call it acceptable input
I also like the idea of ply or something, like an Eames bit of furniture.


I'll also add another model into the thread. It's a sled adapter for the IIcx/ci/Quadra 700 and wherever else that style of metal drive carrier is used. I'll admit the use case is rather narrow: meant for SCSI storage replacements which have 1:1 3.5" mounting solutions. Its purpose is to set the board off of the metal carrier enough to prevent solder joints from shorting.

This adapter has a smaller footprint than the stellar universal adapter meant for other devices. It's only a screw's width more forward/away from the original SCSI and power connectors of that of a spinner drive. I used standard #6-32 computer screws both to secure the board to the sled, and the sled to the metal drive carrier. They thread right in, but might weaken with repeat installations and extractions.

At the time it wasn't directly related and I was too manic to take note. So not complaining per se, just thinking that a bit more input from all the creative types we have around the forums could be mentioned and then linked to a thread like this for further thought.

Maybe an Eames/Danish Modern Inspired Objects or more general thread to include frog design inspired hacks might be a good idea?

Here's a laminated project directly OT for your project. thicken the left leg quite a bit and convert the other to full height from"bottom of TowerIIfx to top" with venting and width to filled out to 5.25" PC FDD width platform at top. Maybe allow provision for power distribution switches a/o ADB switchbox implementation up along the way.


ASCII playtime is up, didn't work anyway. Drop out extra carriage return to lower profilet of the 5.25" PC FDD/CD SlotLoader hack and you get the idea. Buts up against the right file cabinet under desk.

Should have used pencil and paper, but ASCII art is too ingrained in my internet . . . you know . . . WWWfree zone of the day.

Hello. I have a Macintosh II stand, but I think it was late.
Felt cushions are attached to the body and bottom to prevent scratches.

Thanks for the pics of the original stands. It looks like I need to order some felt to complete my 3D clone!

Man, Ive got to get my printer up and running again to print some of those stands, they looks great. Do the 3d printed stand files account for the space needed for felt?

They seem to, there's a gap either side of a Mac II when its slotted onto these stands so you can use that space for the felt.

Mac plus battery door, might fit other models:

Hi all,

thanks for sharing your works! I'm looking for 3D models of the Mac Plus battery door as well as the programmer / reset switch.

@SDUBjed, any chance you still have the files for the battery cover you posted nearly four years ago? My Plus still has its cover but I wired an external 3xAA to the battery terminals, and right now simply pinched the leads by reattaching the cover. It's awful and will probably damage (bend) the original cover over time. So I'd like to make a door with a small port for the wires, so I don't have to cut up the original door.

As for the Mac Plus programmer switch, I don't have one, so I couldn't even take a stab at making my own model.

Cheers

Here are two different battery doors:
Macintosh Plus - Battery door cover
&
Apple Macintosh 128k, 512k, Plus Battery Door

And here's the programmer's switch. Although I think I've seen another one. Can't find it right now though.
Programmers Switch

 

[linkthehero1234]

someone should do the pb5300 battery

 

[mikerofone]

Avondragon, thanks for the links! I tried searching for "programmer switch" on Thingiverse, but hadn't thought to search for "programmers switch". Thingiverse search isn't very forgiving it seems. Googling brought me here, and after seeing the battery door here I simply forgot to also try that on Thingiverse...

Anyways, much appreciated, and the switch is currently printing. A bit of a tricky thing to print, given that there is no obvious ideal face on which to print it without requiring supports in inconvenient places. I'll post my (hopefully successful) results later.

Cheers

It came out well enough: https://www.thingiverse.com/make:1013005

Since Thingiverse ate the photos I uploaded (or they are slow to publish) here they are again:



I'll need to edit the battery door models to add the hole for my cables, so that'll have to wait for another day.

Thanks again!
Cheers

Just just finished modeling a battery door cover for the PowerBook 1xx series. It is up on Thingiverse now.

PowerBook 1xx Battery Cover

my PowerBook was missing one foot, so i replaced both.

also uploaded to Prusa

This is a model of the battery for a Macintosh PowerBook 1400. It fits the existing battery bay, and includes the appropriate slots to align and latch into place. I have three different PowerBook 1400, and this fit in each of them.

You can print an entire battery and insert it as a blank, or pull the model apart to print just what you need.

I made a version that uses an existing battery faceplate to turn the battery bay into a drawer. This was a result of my clever idea to accidentally knock the battery onto the floor while i was measuring it, snapping it into two pretty clean pieces.

Please share any variations you make. I also uploaded this to Prusa and thingiverse.
