Cool Cup Holders? (New 3d Printed Design) (Page 2/3)

This is a really cool and unique design, wonder what material would be best to print it in? (How hot does it get in a typical Fiero interior? 🤔

I would avoid PLA as its transition temperature starts around 60C. ABS or PETG would be fine.

I bought my printer kit for around $150 ten years ago. I didn't had succes printing ABS untill I built an enclosure which helped to maintain the higher temperatures needed to print ABS. A heated bed and an enclosure are a must for ABS.
I use my printer regularly and it has become one of my tools to make parts which are difficult to make otherwise or I cant find in a store. So far I have designed and printed several parts for my Fiero (including cupholders!).

These are made from PETG, as I do almost all automotive stuff with PETG. Pla will warp in the sunlight. ABS fairs well, but I prefer the qualities of PETG, even though I like the finish of ABS more.

On my truck, I have some PETG and TPU parts that have been in place for several years and have survived the heat of the sun both inside and outside the vehicle. Some of these are very large parts, some of them are small. But PETG is great, especially at 100% infill on all small parts, but big parts can be 15%-30% if they aren't all that critical

Are you going to be selling these? Will you be offering different color options?

The Fiero has a bottle holder.

It's between the seat and the door......

Do you have to design the parts in CAD or can you just 3D scan an object you want to print?

I can think of a lot of things I would print if I could just sculpt the object and scan it.

I never 3D scanned an object but sculpting an object to scan it to make it again sounds a bit counterproductive. I can imagine you would do that if it is to complex to model in software.

You can find many printable files at Thingieverse and the likes but if you want to design your own objects you need to learn the basics of 3D design. Any (free) 3D software that can output .stl files could be used. Most of the objects I make are simple basic shapes combined to a final (sometimes complex) shape. The sizes and dimensions I put in are the same as I get in the final product so this is more accurate than handshaping.

I have never done it, so I can't say for sure. But I think I could sculpt a face from clay quicker than I could design it on a CAD program.

I am intrigued by the possibilities either way.

If you changed your design so that the cup holders set forward more and dropped down to the level of the arm rest would that get in the way of resting your arm there?

So I do both sculpting and the sketch/draft style of CAD work, and I find that a part like this takes far longer with scuplting. Thus, for a part like this I tend to use Freecad, which can be a bit painful to learn, but is very competent when it comes to sketching out parts like this.

I was not planning on making or selling these in mass, as they aren't the sort of thing that deserves a high price tag but at the same time take an large amount of material and a very long time to print (I printed the four pieces over a three night period). But I wouldn't mind sharing the files if someone was wanting to try a model as an individual.

Edit: I personally do not like scanning items, as I have not found any success in that area. A fine micrometer and protractor are my choice of tools, and I so far they've treated me well in precise fitment.

Regarding awkward access: my wife's 2020 Subaru Forester has two cup holders side-by side on the center console just to the right of the driver's right elbow. To make it worse, the padded rectangular lid to a little cargo compartment slightly overhangs the cup holders. The lid cannot be slid back.

Bottom line: the only way I've found for the driver to safely - sort of safely - use a cup holder in her car is to reach across with the left arm/hand. At least that way you're approaching the cup holder from the front and not from directly above. Also avoids jamming the right elbow backwards.

Looks like the left hand cross-over technique would work with this thread's cup holder arrangement. Maybe a bit of a torso twist, but what the heck? Don't reach for the strawberry shake in a decreasing radius corner.
