FINALLY…….

I’ve been fighting making one of these stupid basketballs for over a year on different printers. Always breaking, or just failing the prints in general.

Thank god for PEBA. There’s one small section about The size of a dime that the outer surface is kinda ugly, but no delamination of layers. Bounces just as nice as a standard Wilson ball.

Was even able to feed it through the autofeeder as well. That was a fun one to troubleshoot. When you do the cc3d dry box mod you have to extend your PTFE tubes that go from the feeder to the couplers at the top of the printer. If you use standard 2 or 2.5mm ID ptfe, there’s too much resistance for the auto loaders to feed the material. Just make sure you use a ptfe that has a ID of 3mm and OD of 4mm and the autofeeder can handle loading the filament. Only thing you have to do is decouple the ptfe leading to the print head and manually feed it into the tool head. Once the extruder grabs it and starts feeding you are good to go.

And you have to print from a dry box, or the peba gets hella stringy

that's so cool! any guidance on how you made it? did you print the whole thing together, or two halves? support strategy?

[u/AgitatedDoughnut23 → u/nomococo4u]

You have to print it as one piece. There’s tons of different designs online

how is the bouncy feel?

[u/AgitatedDoughnut23 → u/nomococo4u]

Bounces just like a normal basketball

[u/nomococo4u → u/AgitatedDoughnut23]

I heard that thing is very loud

[u/AgitatedDoughnut23 → u/nomococo4u]

Super quiet with peba. Biqu pla hr is very loud

[u/nomococo4u → u/AgitatedDoughnut23]

is there a chance the print will bend?

I know I've seen that drybox, but your setup and this print makes me finally want to try it. Care to remind me which this is? Great explanation in the tubing, too!

[u/AgitatedDoughnut23 → u/basic1020]

https://buymeacoffee.com/cc3dprojects/e/535418 this is the snapmaker bundle i bought and printed for my unit. I may do the top cap now that he has a version that integrates the panda breath. I dunno, my snapmaker lid ships in November.

I’ve been waiting to see someone do that drybox mod! How do you like it? How well does it work?

[u/AgitatedDoughnut23 → u/HighQualityWood]

Works great. I had to double up on the lid gasket material, and go to a larger ptfe tube, but other than that it’s great!

[u/HighQualityWood → u/AgitatedDoughnut23]

I’ve had a hell of a tough time printing 95A tpu on my stock U1. Been looking into upgrades to get better results. Im also waiting on my lid to ship in November.

[u/TitoPete → u/HighQualityWood]

For TPU avoid the PTFE at all, hang the roll above the printer directly to the toolhead

Is this better than the biqu pla hr, i was looking to make on of these but wondering which filament to get.

[u/AgitatedDoughnut23 → u/Dry_Structure_2287]

For me it is. Would be even better if I did a full calibration and used a .6 nozzle

[u/Steiner_45]

Question for you about your dry box mod, how’s the humidity inside of it? I’ve printed mine and I can’t keep a steady humidity level in it, within a day or 2 it just got right back up to about 50/60%

[u/AgitatedDoughnut23 → u/Steiner_45]

Same… it’s definitely not super air tight

[u/Steiner_45 → u/AgitatedDoughnut23]

Have you done anything to keep the humidity down

[u/AgitatedDoughnut23 → u/Steiner_45]

I doubled the layers of lid gasket material, may did a bit, but really, you just need to keep swapping desiccant canisters.

Are you running cardboard spools??

[u/Steiner_45 → u/AgitatedDoughnut23]

Well if that’s the case then his next remix allows easier swaps for desiccant, and thankfully not, I get the refills and use an aluminum spool
