Pressure Gauge

I found this pressure gauge buried under the pile of un-used parts. I can’t image when I would have purchased a 10,000 psi pressure gauge…made in China. My guess is…I didn’t buy it. It’s not up to the quality my customers expect. It probably came on some equipment and we replaced it. It does however have a unique “Danger Zone” graphic on the dial. I figured this might have artistic appeal.

It was uploaded to CG Trader and I got my first sale 3 days later.

Residential Oil Tank

My day job has me designing an oil recovery system for a hydraulic coupling. It’s a complex oil system that uses a residential oil tank. I was surprised to find little in the way of online resources for such a common architectural 3D asset.

So I spent a little extra personal time on this model. I modeled the tank in Blender 2.9. It’s a 275 gallon Granby vertical oil tank. It is available at CGTrader:

O.C.B.P. Life Guard Chair modeled in Blender

3D Models in Microsoft Office

My latest model of an Ocean City Beach Patrol lifeguard chair was created in Blender and exported as a GLB file. The GLB files can be imported into Microsoft Word, Excel, Powerpoint and many other Microsoft products.

Loading 3D models in Word

In Word, click “Insert” in the menu. Then click the black down arrow next to “3D Models”. Select “This Device…”

Browse for the GLB file you want to import.

After the file is loaded, you can rotate the part, scale the size, zoom in or out and even create some lighting effects.

If there is any interest, maybe I’ll do a video showing how to use the model in Microsoft Office products.

Blender Tutorial: Knurl Mesh

Knobs have knurls. A knurl is that hatch pattern found on cylindrical surfaces. They are easy to create on a lathe and, believe it or not, it is easy to model in Blender. Here’s how.

These instructions are for Blender 2.8

Start with a cylinder. Shift-A, Mesh, Cylinder

Blender Knurl Tutorial 1

Set the cylinder parameters to a radius of 1 with a depth of 2 and 60 vertices. Select nothing for Cap Fill. Continue reading

Resistor Collection

Wasting time is such a waste (duh). Once you have modeled an object, it is great to have a library of part. The question is…how do you organize them in a way that you can find the part you need and easily import the part into you new design.

Today was my first attempt a building a library in Blender. I created a Blend file with 57 different configuration. There are 19 different resistance values (as indicated by the resistor color code) and each resistor is saved in 3 different mesh forms. The first form is straight. The 2nd form has both terminals bent at 90 degrees for horizontal mounting on a breadboard. The 3rd formation has one terminal bent to 180 degrees for vertical mounting on a breadboard.

Picnic Table

3D models can be from your imagination or from real world items. Today’s model is from the real world.

I modeled a picnic table from one that is available at Home Depot. I used the online photos in fspy to get the camera position. The fspy camera positions and the phone are then imported into Blender with an add-on. I then drew and aligned picnic table elements in Blender. When it was all done, I scaled it to real world sizes and added weathered wood materials. The materials were created with overlapping UVs. This allowed me to get decent resolution without using huge images.

The model is available at CGTrader.

Collection of Knobs - 3D models

A collection of knobs

2 posts in one day. That’s a first.

I’ve been working on this collection of knobs for a while. I thought it would be simple. But like most things…simple is rare. I ran into difficulties controlling fillets in meshes that were sub-surface ready. The model would look good until the sub-surface modifier was added. You can get some strange looking artifacts if you don’t have good topology.

The collection of knobs is available at CGTrader: https://www.cgtrader.com/3d-models/electronics/other/collection-of-12-knobs

 

Air Pressure Regulator

Today I received an air pressure regulator that I will be using in an industrial brake. The brake has a pneumatic powered oil pump.

I first made the model in Solidworks. It was exported as an STL. This makes a horrible mesh for Blender. Triangles aren’t necessarily bad, but long triangles with sharp corners are not good.

I recreated the mesh by over the top of the imported file and then shrunk it down on the surfaces of the imported model. I then created material map files. For this model, I made a diffuse map, a metallic map, a roughness map and a normal map.

This model is available at CGTrader.com: https://www.cgtrader.com/3d-models/industrial/part/air-pressure-regulator
