Adapter to attach a Nikon camera to a focuser for prime focus photography. Print instructions Unlike the example in the photo, you might want to print this in a matte black material to avoid reflections. Print Settings No rafts, no…
This design was inspired by the Impossible Pyramid Passthrough and the question “can you make it spin?". The design is completely from scratch and in contrast to the pyramid, this uses two separate, subtly different shapes for the…
This is a module intended for use in other openscad files. This module generates a frame that can hold a Wemos D1 Mini. This frame can be used in enclosures where the PCB can be clipped into place without screws or glue. Print…
This very simple LED fixture makes the reticle in a polar scope visible when aligning a telescope in the dark. You will need to physically dim the LED, for instance by covering it with nail polish. Features battery compartment also acts…
I needed a slightly larger cover plate to cover an overly large hole for a wall switch in the house. The regular BJ cover plates came a bit short, so I created this one. The STL is of the regular size, but the freecad model has parameters…
Our budgie likes to keep an eye on me while I'm at work. Unfortunately, when he drops a visit, he also drops other things. This perch sits on top of the monitor and has a tray to prevent bird droppings from falling in inconvenient places.…
This is currently still a work in progress: Enclosure for a WiFi-connected passive infrared (PIR) sensor. This device consists simply of an HC-SR501 PIR module and a Wemos D1 mini board. The enclosure allows for the sensor to be pointed.…
This mini engine order telegraph is intended to set a home automation system in a specific "mode". The device has 5 positions; the actual position will be sent through mqtt, where it can be picked up by home automation systems. The…
Simple tray to hold telescope eye pieces. This tray will accept a mix of 2 inch and 1.25 inch pieces as it is. It's fairly easy to adapt the script to create different dimensions and mixes of sizes. Near the top, the included openscad…
Hamster wheel with hall sensors for rotation count/speed/direction. The wheel runs silent on a 608 ball bearing. The wheel is decorated with the names of our two hamsters (Pjotr and Ilya, they're Siberian dwarf hamsters), but there is a…
These pins can be used to support LGB or garden rail track on somewhat uneven terrain: place the pin under the rails and push them into the ground to keep the rails at the right height. The two protrusions on the top are spaced so that…
Enclosure for a WiFi-to-serial bridge for my Skywatcher EQM35 Pro mount. The electronics also implement SNAP-port behaviour for camera control. Description of the project, including link to software sources and electronics are on this…
This is an alternative base for the "Progressive Detail Moon Lamp". This one swaps the rechargeable battery for a very simple, throwy-style LED + CR2032 battery combination. The battery holder also acts as a switch (the battery clicks…
These are all currently available results.
