Printed or milled request - Sorted

Just my 2p worth...

I'd consider modifying your design to put the switches horizontal and use roller lever operated by the green bits as a cam. The way you have it relies on the carriage stopping fast enough not to overstress the switch. Hitting the limit a few times could compromise the switch reliability.

I see now how you are mounting it, but just a flat plate at the bottom would still work with a washer in the slot and a bolt through.. very small parts like that, having to print it on end (because of the lugs) are difficult because plastic does not have time to cool as it is building up.
Also the slots where the switches are mounted don't need to be there (that little channel could be filled in).
What size bolt holes are they for the switches. Clive

The holes are for M2 bolts.

Thanks

A fan is really a necessity, not just for small parts but also for bridges. One trick if you haven't got a fan is to print multiple copies or print something of similar height at the same time..

Yes I agree I printed 3 of the small parts because of the fact that the print head can then move between them and the part has a chance to cool down.
I have 2 printers one set up with ABS and the other with PLA but very small parts are always tricky. Clive

Can't you just insert a periodic pause into the program so the part has chance to cool down?

Yes you can and is often done so. You can get the print head to circle away from the part but then other issues come in to play ie. ooze from the head even though the filament is retracted between moves. Its all a bit of a balancing act. Clive

Agree with Irving.!!. . . BUT . . . there's another plus to using Cam or ramp.? You only need 1 switch which travels not 2.!!

Hi There.

Having been lurking around this forum for a while i figured it was time for me to chime in.
Did you get this sorted?
If not i might be able to help out.
I have a fair bit of experience with 3D printing and i see no reason why this should not be printable.

Anyways... let me know if it's still relevant.

Best.
