One of the last steps of assembling a Prusa i3 MK3 3d printer is to manually adjust the Z height. As I adjusted my printer’s Z height, I began to wonder what the Z height calibration looked like on my older printer, a Lulzbot Mini. At the same time, I became curious about what size that Lulzbot Mini can print. A simple test print answered both questions.

I’ve been interested in the Tracery in Gothic Cathedrals – the delicate patterns in stone walls and windows – for years. In this post, I show you how to design of one type of Gothic ornament, using FreeCAD. You can follow along with the FreeCAD file on Cults3D, or you can use your favorite CAD application, such as Autodesk Fusion 360.
Having just spent 24 hours, spread over 4 days, assembling a Prusa I3 MK3 Kit, here are my notes to help you assemble your own kit.
I often 3D print screw-top parts to replace broken or missing parts. For example, we recently installed media (blackout) shades for our skylights, so we can watch movies when the sun is out. Our family room ceiling is quite high, so the pole and hook designed to open and close the new shades is too short.

An idea’s been forming in the back of my head for a while: that it should be possible to estimate the amount of 3D filament left on a reel by simply weighing the reel with its filament, and subtracting the reel weight. Sounds simple, no?
Today I realized that it may be possible to modify a printer to give a live estimate of filament left on the currently-mounted reel, by “live weighing” the reel, and knowing the reel weight and filament density.
NOTE: Go to the updated post Making a 3D Printed Name Badge, Version 2. The tools have improved and changed in the years since I’ve written this original post.
Last month at the Portland OR 3D printing Meetup, someone suggested we should all make our own name badges so Shashi wouldn’t need to bring as many “Hello, My Name Is” paper tags to the Meetups. Game On!
In this post I explain how to make your own, two-color 3D Printed name badge just like mine.
Continue reading Making a 3D Printed Name BadgeI’ve found 3D printing to be perfect for creating replacement parts for the various things that break around the house. Recently I realized that I could make a replacement for the armoire door clip that had been bent beyond recognition over the years. This post details how I designed and tested the 3D printed replacement, including a checklist at the end of this post.
