Here is a simple 3D model for standing a shampoo, conditioner, detergent, or liquid soap bottle upside down. The diameter of the hole for the bottle cap is 31.5 mm. If you need a stand for a different diameter, let me know, and I’ll generate it, or you can download the Fusion 360 or STEP file and modify it yourself. I printed mine in white PETG with 15% infill.
I have been using the Articulating Pi Cam mount with my Prusa MK3S. The joints between the links were coming lose all the time, and the 3D-printed screws were breaking when I was trying to tighten them. I designed my own arm for the mount, which:
This article describes a very simple way to level the bed on a Prusa MK3/S/+ virtually for free. I’ll show you how you can use a beer can to make metal shims, and then easily install those shims to achieve a nearly perfectly flat printing surface on your Prusa. I will also discuss the reasons to do (or not to do) this, and compare this method to the fairly popular “Nyloc Nod”.
Raspberry Pi’s main downside (as far as using it as a router) is that it has only one Ethernet port. This can be overcome by using a USB Ethernet dongle to get an additional Ethernet port. I did not like that idea, because USB dongles are not designed for 24/7 operation. I stumbled upon a forum post that suggested using VLAN tagging to carry two virtual interfaces through the only Ethernet port of the Raspberry Pi, thus eliminating the need for the USB dongle. This article is a quick how-to for setting that up.
I have a pair of Snoqualmie Pass tires on my road bike, set up tubeless. I absolutely love them, but I got a small cut on the sidewall of the rear tire. The tires still have a lot of life in them, and, considering that they are not so cheap to replace, I decided to try repairing the cut.
[Update 4 months down the road – May 2021] The repair is holding just like the day I made it.
I designed and printed a large New Year tree toper of Flying Spaghetti Monster emblem. This post is to share the devine noodly goodness (or is it godness) with the world. My 3D printer can print up to 25 cm by 21 cm, so this model is split in three parts to be glued together.
When looking for a pocket hole jig, I had difficulty choosing between the various versions Kreg offers. On the one hand, I wanted the Mini because it is the smallest jig that can get into tight places, and is very cheap. On the other hand, I wanted the jig to have a nice fence for easy, repeatable pocket holes. I decided to design my own fence system for the Kreg Jig Mini, which, I believe, is more flexible than the fence that comes with the Kreg Jig 320. The fence I designed allows for a greater range of adjustability and features alignment windows for precise positioning of the jig on a drawn pencil line.
Did you ever try to weigh a spool of filament on a small kitchen scale? If you lay it flat, you can’t see the scale’s display. If you try to stand it up, it rolls off the scale. This simple jig is designed to solve that problem. With it you can stand the spool of filament up on your small scale and easily read the scale.
I designed a thread stand to be used with thread cones and cross-wound thread spools (for sewing machines that don’t have horizontal spool pins). To make the stand a bit more substantial, the base can be filled with something heavy, like sand, lead shot, or bearing balls. The conical spool cap has two diameters: wider for bigger spools, and narrower for smaller ones. To make it you need a 3D printer, some glue, and 12-gauge steel wire for the center pin and the arm.
I designed an all-in 3D printed table saw throat insert. It features changeable dovetailed zero clearance strips that are easy to make from 1/4″ birch plywood. The insert allows full range of movement of blade and splitter (height and tilt angle). It has leveling feet for perfect alignment with the table surface, a safety tab, and fine fit adjustment screws. It can be printed on most common household 3D printers. While it is tailored for my particular table saw, I’m hoping that the design can be tweaked to fit other left tilting saws.
