I printed it in PLA+ and it prints and works fine.
I use it in my diy encloser for the MK4.
I did not understand what the holder_nut is needed for. So I left it out...
Thanks for the nice print :-)
@AlexP I'm glad you liked it! :) Thank you for posting a make!
The "holder_nut" is to keep the holder from collapsing if there is no phone mounted. Otherwise the bolt will just fall through the upper leg. But when a phone or something else is in place it serves no function. (edited)
@christofferra_319142 Thanks, now I got it :-)
Nice model. Maybe my printer needs calibration but parts were a tight fit so using pliers was necessary. Seems to be holding my phone well
Honestly, I’m not sure how everyone got theirs assembled. Both of the double rods have one right handed thread and one left handed thread. The phone holder is a right hand thread and the ball is a right hand thread. Without destroying the threads on one or the other, it’s not assembling.
@giganto53_81340 , thank you for pointing that out. I'm a bit confused as well, did not notice that.
The ball may be a bit hard to screw on I remember, probably it was destroying the thread as you point out just that I didn't notice it since it stays together without a problem. Actually those small threads are a bit fragile to begin with. The purpose is to just thread them once during assembly, probably thats why I didnt notice.
I will update the model with the correct thread as soon as I'm able.
@giganto53_81340 , there's a new verision of the double ended rod now, rod_double_v25 with both right hand threads as should be. thank you for pointing that out.
Great model, perfect for what I needed. @christofferra_319142 was nice enough to make a mount for flat surfaces instead of extrusion channel on my request.
The only issue I had was I had to use 2 vice grips to do up the lock nuts very tightly or it wouldn't support the weight of the phone. I did use PLA+ (eSun) instead of PETG as was recommended, so maybe that was a factor.
@BradleyM1_171049 looks nice! Glad you liked it!
Honest feedback. Concept is good, and has flexibility built in. I was able to print all the parts without any supports. I did the lock nuts at 0.15 layer height with wall order inner+outer. This did not cause any problems and they printed clean.
The bad part is that ball to arm screw is a very weak point. Even with a slight knock I broke 3. So maybe a combination of printing them out of layer plane and beefing up walls will help.
I personally found it to be very wobbly. Since it is mounted to frame, it was shaking during printing and sure enough after a few minutes it loosened everything and phone fell off. Here I think some sort of support leg in the middle to offload the weight of phone will help.
I will still give it 5 star because it has high potential.

@golekipro Sorry I forgot to mention that I always mount the phone vertically, not horizontally as you have shown in your pictures.
@golekipro I think you will have to solve that problem by glueing on some rubber. maybe rubber bands around the claws will help?
Plastic will always be a bit slippery even with some added roughness.
An outstanding phone holder for Prusa Mini+. PETG would be perfect choice for this model.
