I’m trying to 3D print this model to act as packaging for plants in delivery. The two halves of the packaging will slide over the pot and connect together, keeping the plant held firmly in place in the bottom half of the packaging, while leaving room for foliage at the top.

The problem is that I can’t make a model strong enough. The base of the model that rest against the hotbed is very strong and hard for me to snap. But the arms that extend from the base are very weak and snap with little effort.

I’m using ASA filament, which is very strong and flexible. I also have polycarbonate if that would be a better choice. I’m using a Rostock Max V3 3D printer.

Up I tried putting support for the arms on the model, but that only made the arms snap where the supports ended.

I can’t really see that good in the pics so a little help by marking the areas having trouble and showing better what is happening would be good.

My guess is that at the joint that is breaking there may be a couple things going on. One is just to redesign it. The other could be related to infill, extruder temp and layer bonding.

Yeah, these type models are difficult due to the limited orientation options. Basically what is happening from what I see is that your model snaps on the layer lines. So when printing, we try to rotate the model in a way that it won’t snap on the layer lines. This model is extremely difficult due to the fact that its just outlining that has some ribbing added and thickness added. (Don’t be offended, that’s just what I see and how I can best describe it)

So, in order to keep it from snapping where you don’t want it to, you need to rotate it so the parts that you don’t want to snap are laying flat on the bed or in that orientation with supports. Your first picture would be an orientation that would help eliminate the problem. However, you would have to use a lot of supports.

For this one, try separating your sides so they are there own model and use locking guides on each model so you can glue them together. This way you can lay them all flat on the bed and have a much stronger model.

I’ll start by saying that my printer uses 3mm filament

If I have the room to do it, I would design the extended pins so that they are actually a tube.

The tube would have a 3mm hole in it.

After printing, I would cut pieces of 3mm filament and glue those into the tubes.

That would make your pins very much stronger.

I’ve done that with several projects and it works out pretty good.

I hope I’ve made myself clear and

I hope this helps you in some manner.

Print it in nylon.
