alexis is there an STL file available for those pods ?

I have been tinkering with some 3dp pods, the prototypes have been printed in PLA, just wondering if that would be strong enough or if I should use PETG or something else ?
RE: 3DP Pods - Kevan - 26th-Jun-23
PLA is strong enough unless you're straining the layer bond with screw adjustments.
If you're holding the motor in with screws it's probably best to put washers under the screw heads to spread the load, again layer bond.
Strongest will be nylon but a pig to print and in reality too flexible.
RE: 3DP Pods - AlexisGaitanis - 26th-Jun-23
Absolutely,there is a strong chance PLA will brake after a few times inserting and removing the motor.PETG is the choice.
RE: 3DP Pods - Kevan - 26th-Jun-23
PC would probably be a good choice but not so straight forward to print with.

PLA works fine...If you make sure the fit isn't snap-in tight. I have been using PLA pods for quite some time, but I do run a bead of hot glue along the motor to hold it in.
PLA is not quite strong enough for snap-in pods and will send/distort under force so you have watch your dimensions....but it can work.

Would agree with Chappyman here, PLA or PLA+/super/Tough is more than adequate for pods the key as stated above is design the pods for the process and material used.
Simple rules keep the flexing of vertical walls to a minimum, ensure sufficient wall thickness is used i.e. thicker than injection moulded pods and buttress the walls where possible.
The other point to note is that PLA varies greatly from manufacturer to manufacturer, Ive had PLA that has a beautiful layer finish but is too rigid so will snap if flexed. When I have new manufacturers filament I make test wafers both horizontally and vertical and check to see how they flex and how good layer adhesion is using the slotted jig shown below. By placing the wafers in the lower jig slots then bending downwards to the base and moving up the slots until the wafer snaps or bends and does not recover. This testing also helps with dialling in the printer settings for nozzles temperatures and layer height.

For Kevan....A plastic pod with a motor held by two screws?
How do you support the motor other than the screws?
Oh and to continue to question.... spherical bearings? Why?
RE: 3DP Pods - KensRedZed - 28th-Jun-23
Spherical bearings or bushings are self aligning.
