This cannon was designed by my grandfather J.W. Mark in the 1980's. I dont' know if he took an exisiting cannon as inspiration or that he designed it from scratch. 

He created it in wood and brass. The second image shows the original.

This is a reproduction of that cannon as a 3D-model that is 3D-printable. My printed version is shown in the third image.

This is a gearbox for the first version of the Teptron Move.

The Move is not strong enough to raise big blinds.

This gearbox slows it down, but also makes it much stronger.

I'm able to move 2 meter wide and 1.5 meter high light blocking blinds with this assembly.

I made this thing to raise my couch just a few centimeters (4 cm). By using just two of them at the front the effect is that the couch is tilted back a little.

This is a replacement for the flimsy lens cap that came with the camera and that keeps falling off.

This lens cap clamps onto the outer rim of the lens. It has room for the lens to extend if you accidentally switch on the camera with the cap on.

Layer height: 0.2mm

After printing use some electrical tape on the inside of the lens cap to prevent scratching the camera. The cap was designed to be used with tape applied.

This is a replacement for the standard axle of the bean stirrer in a Sarista bean funnel. The original one "expires" after about one and a half funnels of beans.

When you replace that one with this, the bean funnel can be refilled forever.

To replace the axle (assuming you have already created some kind of opening at the top to make refilling possible)

Layer height: 0.2mm

1. Remove the bottom plate (the part with the opening that exposes the lock-icon) by inserting a flathead screwdriver between the rim of the funnel and the edge of the bottom plate. The plate is very flexible, but will come off with some effort.
2. Insert a small philips-head screwdriver through the opening at the top and push down on the center of the original axle while supporting the underside on both sides of the rotating part in the middle. This will also take some effort.
3. Replace the old axle with the new one and use needle nose pliers to push down on the stirrer from the top. Open up the pliers a bit and place the tips on both sides of the opening at the top of the stirrer. Push the new axle up and it will click in place.
4. Reattach the bottom plate. Be sure that it has snapped back in place on both the insde and outside.
