Printed or milled request - Sorted

[Dwayne Dibbley]

Hi, would anybody be able to make / mill these:

Z limit switch holder RH.stlZ limit switch pusher.stl

I need two of the pusher and one of the mount, could it be milled out of alu / plastic? or would 3d printing be the best option?

Thanks for looking

Very suitable for 3D printing - you'll get a little bit of distortion on the holes but as long as they're just clearance holes for bolts they'll be fine.

Bit busy at the mo but might be able to do it if you don't get any other offers.

I was just looking for something to test my printer. It says it will be done in 55 minutes, might be okay might be a piece of dooh

Quite interesting what units is the stl in. ie what size are they and are they designed to interlock with each other?

I have printed these off as to see what they are like but do you need those bits that stick out on the side of the pushers 3D printing is not good with overhangs so they have to be printed vertical. I think the model could be improved for 3D printing.

If you pm me with an address I will send you them foc. Clive

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.

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..
