Hello Again;

I decided to Print your case.

I did get it to close.
With great force and as you can see in the photos cracked the top rim on both sides.

Do not worry about the lines they happen when I try to use very little infill,
without first printing a 3 layer outer wall, when using sparse infill.

In Short was 3D Printing A simple draft of this Model to save material.

After removing the lip on the side that had cracked the worst.
I found the the top lid snaps in nicely on holds very well.

Though adjustments will need to be made as the lip of the back wall is bowed outwards.

Hi Robert
For me on parts that fit I make a 0.2mm gap. I find the print is 0.2mm bigger so I get a good fit.
It saves all the sanding afterwards.
So if I have a hole that an 8mm steel pin has to go in I make the hole 8.2mm.

Then jumped in learning the Free for Hobbyist/Personal use Fusion 360.

Fusion 360 a great Program thou not knowing CAD, I was jumping from Fusion 360 to You-Tube Videos learning,
As I went and my first Project turned out fairly nice See Below.

So Keep plugging away you will learn to model using Sketchup
I have been paying with Tinkercad most of the day and it certainly is alot easier to use, I however want to find out if there is a forum that is dedicated to Tinkercad? I did the introductin lessons and have now tried to do my own first design.

A simple 20 x 20 x 20 mm box with a 15 mm diameter hole in the centre that does not go all the way through. So 18mm deep. I can do the cube and the cylinder but cannot combine them. Thus want to find out where to get help

Many thanks

First Create the 20mm cube, then create the 15mm cylinder 18mm in depth.
Using the Align tool Raise to the Height to the Top of Cube then center models.

While the two are still selected group models

How many sides did you give the hole.
