I recently needed to print a replacement door for the Whirlpool dishwasher’s detergent dispenser. This post details my adventure, which took three prints to get it right.
For the short version of the story, see All3DP’s brief page on how to stop ABS print warping. For the whole story, read on.
LATE UPDATE: Prusa’s excellent post on food safe printing basically says ABS = bad and that it’s really hard to make a safe 3D print regardless of the type of filament. In my opinion, you’re probably better off buying the Whirlpool replacement part rather than printing something that will harbor bacteria and fungi.

If you’re interested in Gothic architecture, you may have seen my post on Designing a Gothic Trefoil. In this post I walk you though the design in FreeCAD of a simpler ornament, the Gothic Duefoil: a circle divided into two arches, which are themselves each divided into three lobes.

A while ago I bought a beat up cuckoo clock on eBay, to practice cuckoo clock cleaning and repair. Its face was missing most of its numerals. In this post, I describe how to use a 3D printed template to glue the numerals on a cuckoo clock’s face.

I recently bought and assembled a Prusa i3 MK3 kit, and decided to prepare for printing emergencies by printing a full set of replacement parts as soon as the printer was working well.
I’d found, in using my other printer, that even high-quality printed parts do eventually delaminate under stress: after two years, that printer’s X and Y idler supports developed fractures. Because I couldn’t print the replacement parts (and because doing the replacement seemed daunting at the time), I wound up sending that printer to the factory for repairs.
I’ve also seen notes and videos from people recommending a set of replacement parts as a backup, in case you break a part while adjusting or doing maintenance on your printer. Having replacement parts on hand is also a good preparation for helping a 3D printing friend when their printer breaks.

I used to think that 3D Printer extruder tension – how much pressure the extruder hobbed gear exerts on the filament to move it forward – was a pretty forgiving thing. At one extreme, there’s “so loose the filament doesn’t feed” and on the other, there’s “so tight the extruder motor binds”. I thought everything in between was ok.
My assumption was confirmed each time I read advice on how to tune a misbehaving printer: people rarely mentioned extruder tension.
My recent fight to fix a bad print taught me that incorrect extruder tension can make a huge difference in your print quality after all.

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 bought my Lulzbot Mini 3D printer almost 2 years ago, and I’ve loved it. While I’ve read others’ troubles trying to get their kit 3D printers working, or calibrated, or repaired, or trying to get their prints to stick, or not stick… my little Lulzbot Mini has been chugging reliably along, printing accurate objects every time.
Now, inevitably, I have to admit my printer is showing its age, and that it’s time to get my hands dirty with a little maintenance.
