Beginner's CAD Phone Holder

This is a phone holder I made in FreeCAD. It is the first, technically, "successful" project I've done that I did on my own. Other than checking the beginner video that shows me on how stuff works in FreeCAD, there was no tutorial I followed for modeling a specific design.

I know the phone holder is not good. In fact, this is a recovered file I thought I lost from the program crashing via user error. I thought to upload it, partly to document and get feedback from anyone who knows FreeCAD.

My next model is going to be a phone holder... but with a more intentional design I sketched prior to winging it.

 Issues I Need To Work On

• Problem: I need to make better measurements.

  • Solution 1: Calipers, yes. But also making sense of the measurements and learning to apply said measurements properly.

  • Solution 2: Need more clearance for phone hook/slot.

  • Solution 3: Understand printer's dimensional accuracy.

• Problem: Improve my sense of scale while working in the digital environment. It can be hard to understand when it is impossible for me to visualize.

  • Solution 1: Photos for reference and with drawings to understand measurements I've taken.

  • Solution 2: Digital mockups of the real thing can help get an idea of proportion and scale.

• Problem: Starting without any reference causes me to blank out and have issue with designing the model.

  • Solution: Use reference images. However, working with my own sketches is better because I can draft a design with all the elements I want and to visualize what I'm thinking of.

Print Settings & Info

I provided the .3mf file. It might show what the settings are, but I'm not sure:

• Slicer: Orca 2.4.0

• Printer: Qidi Tech Q1 Pro

• Filament: Matter Hackers Tan Build PLA (normally I use white)

• Layer Height: 0.2mm

• Infill: 10%

• Walls: 3

• Support: Yes - Tree (Auto) - 30 Threshold Angle - On Build Plate Only

I didn't really try with making the print settings good. I just wanted to see my digital model printed out to get a sense of what I made in my own hands. As expected, not really good. But I did learn how difficult it is to make an accurate slot/hook gap for where the phone is intended to be held.

Next phone holder project notes:

1. Make two versions. 

   1. A hooked one for better security.

   2. Flat holder for better view.

2. Do not make it so massive. Needs to be in good proportion for the phones I intend to use it on.

3. Needs to be stronger in design. Rather than the big, flat base in this one.

4. Needs to be NO SUPPORT structure design.
