This is a replacement joint for a standard folding chair.

*** This model is for front left corner joint of the chair.
*** You may need to mirror the model if you broke the front right one.

The original piece breaks easily, hence numerous broken chairs can be found in parks and on beaches.

This replacement is to be printed with 75% cubic infill and 8 layers of shell to be strong enough.

Replace the broken one by using screws instead of flimsy rivets used by the manufacturers to secure chair legs and the joint. You will need a couple of screws, a few washers and two lock nuts.

This is the remake of my previous cat collar.

UPDATE OCT 2023:
Added an STL file with blank collar (no name on it; emboss yourself or use a sharpie :)

Re-designed after extensive field trials by Alice - my adventurous outdoor-access black cat.

Collar length is Ok for a smaller cat; you may need to fiddle with it a bit if you need a longer one (given that your 3D printer is capable of handling the size you need).

This version features cleaner design, better shape and the latch that is easier to undo but doesn't come undone accidentally.

It is still a breakaway collar, which means that your cat won't strangle itself if the collar catches on something. In this case cat's desperate effort is enough to tear the collar and free itself. The breakaway perforation is hidden under the latch, therefore the collar maintains its comfortable oval shape.

To reduce the risk of the collar getting caught in the bush make sure to measure your cat's neck and adjust the model length. The included model is good for the neck of a slim cat; if yours is bulkier, you will need to elongate the collar before printing. Read how snug the collar should be - there are lots of info on that.

Always print one extra collar and tear it by hand to make sure it tears with moderate force your cat can develop in distress.

Emboss any text/logo you wish. This model prints very well with 0.2 mm layers and 0.2 mm emboss height. It's just about 1 gram and your cat will hardly notice it.

This is a desktop stand for a microphone, a photo flash or any other device with a standard hot shoe mount.

It allows 3 positions: horizontal, 20° and 30°, which is useful to aim a microphone at the speaker from desk level.

I use it to put the Rode VideoMic Pro on the desk directly before the speaker to minimize room reverberation etc.

This is a stick-on cover for a standard North American household wall switch that prevents it from being toggled by accident.

With this cover attached you won't be able to flip the switch by brushing it with your shoulder, hitting it accidentally etc.

Useful where a wall switch controls sensitive equipment, such as a furnace or (as in my case) cuts power to the outdoor light replaced with a smart floodlight with integrated security camera (guests often flipped this switch at the front door thinking that it turns on the overhead light).

The cover has a hole in it so that you can flip the switch with your little finger easily if needed. Inside clearance is sufficient to accommodate switches that stick out a little (not flat with the faceplate) due to subpar installation.

Use some double-sided adhesive tape to attach this cover to a switch and enjoy )
