Help and advice ( small spacers for CPU cooler )

[faceman123]

I've never used CAD, but I need to make these cylinder spacers



Are there any websites where I can make these? The spacers are 10.5mm tall, 12.1mm wide, and 5.6mm in diameter. The are very small and I want to print four of them with a material that can withstand 95C. If anyone has any ideas on where and what material I should use, I'd really appreciate it. lastly if someone could suggest a cheap place where i could get these printed

Tinkercad is a good, easy to use, free CAD website. Onshape is a good and more complex, free for personal use, CAD website.

For the material which can withstand 95 degrees, I have no experience but that'd have to be some engineering type filament which would, most likely, need an enclosure to print.

When you say 12.1mm wide I guess you mean 12.1mm outer diameter with a 5.6mm hole in the middle?

I'd give them a go but the only material I have to print with would be PLA, pretty sure 95 would be a problem for it stability wise.

I could CNC some for you if you like? We have a syntactic Foam (dont worry it is hard not "foamy") at work which is stable at those temps, if you dont fancy that I could machine some aluminium ones?

How much of a hurry are you in?

Tinkercad already has a pre-built cylinder, all you have to do is input sizes, really couldn't be easier.
Export the file when finished and send/give that file to someone with a printer or one of the many small 3D pring concerns.

As for filaments that can withstrand 95 C .
ABS and ASA have high Vicat softening temperatures (whatever they are)– rated as 97ºC and 98ºC respectively.
Failing that a whoope-do "engineering" filament will be needed .
ABS certainly requires an enclosure (gives of some serious fumes and draughts etc adversally affect it).


More than you ever wanted to know about physical properties of filaments

Best Heat Resistant Filament Materials for 3D Printing

The article explores what heat resistant is, outlines the heat resistance of 3D printing filaments, plus advice on choosing the best filament for heat resistance

www.filamentive.com

According to that ePLA would be suitable but would need to be annealled.

If I remember Sketchup has a free web browser version which can easily do what you want.

Why do the spacers need to withstand 95C? That's pretty hot for a localised temperature. ABS has a glass transition temperature of 105C so should be fine at 95C.

I printed a mounting bracket for my waterblock (so I could use an old waterblock on a new form factor) out of ABS which has done well.

Hi All thanks for the replies, not in a rush omg - if you could you would forever be a legend - I would be happy to pay ! yep those dimensions are correct

Yeah not a problem at all, DW about paying....I'll do it at work lol.

I'll try to get them to you some time next week, bit hectic here just now. Send me your address and I'll get then sent out as soon as I can. @faceman123

You're an absolute legend. I messed up with the measurements, its 10.95mm high (if not possible, 10.90mm) I owe you big time! I'll send you the address
