We’re once again taking a dive into the bargain bin at PCBurn, this time for PETG filament from Amazon. At 12.83, shipped, it’s certainly one of the cheapest filaments I could find. Normally I’m leery (despite what the cheapest PLA on EBay videos I’ve made might have you believe) about running cheap filaments through my…

Motorized Turntable for Video, Photo, and 3D Scanning (DIY)
Have you ever wanted to take a video, photos, or scan an object? Do you need a motorized turntable to move the object while this is done? Then have I got the design for you. Maybe. As it turns out an (ultra) cheap louver stepper isn’t the easiest type of motor to step (relatively) smoothly.
Prusa i3 Mk3: Rewiring the Failed Heatbed
The Prusa i3 Mk3 has had a heatbed failure. The problem’s diagnosed and we’re re-wiring the bed to get it heating properly again.
Heated Bed Cable Replacement on the Prusa i3 Mk3
Recently the heated bed failed on my Prusa i3 Mk3 (from Prusa 3D). But on the up-side it wasn’t the bed itself, but the cables. So I seized the opportunity to make a video of the troubleshooting process. There’ll also be a follow up video on what replaced the original cable.
Box Fan Filter Variable Speed Fan Build
Building your own box fan filter is a great way to reduce the amount of dust in your workspace. I’m going a step further and adding in a variable speed motor control!
Cheapest PLA Filament on Ebay Print Quality
3 months ago I set out to buy the cheapest PLA filament on EBay and see if it was total garbage. And I’ve now printed off about two thirds of the spool. What’s do the prints look like after printing out a pound and a half of plastic?
IGUS Drylin Bushings Removed (for now)
Counting the IGUS Drylin bushing test as a success I’m moving back to bearings. For now. Here’s why.
Drill Press Squaring (with 3D Printed Tool)
I was attempting use a Craftsman bench press to center drill Titanium bolts with HSS drill bits. It didn’t go well so I’ve made a tool to square the table.
Igus Drylin Bushings: Replacing Bearings on a 3D Printer
My Prusa i3 Mk3 printer’s LM8UU bearings were acting up. It could’ve been an issue with the installation. Or they might’ve just been junk out of the box. Regardless, it’s time to replace them.
With three Igus Drylin bushings in-hand I’ve decided to swap those in on the printer, at least temporarily.
Improved Filament Spool Holder (with optional motor)
If you need a spool holder that does the job and has an optional mounting area for a DC brushless motor, here it is. I still need some refinement of the motorization option. But it’s otherwise functional. Sure, there were quite a few other spool holders. None of the ones I browsed on Thingiverse had…
