Simple and quick to print wall mount bracket for the Acurite Temperature and Humidity Sensors.

Acurite Temperature & Humidity Holder

Easy to print Raspberry Pi and (optional) buck converter case for clean mounting on a Prusa MK3S. 

Everything prints flat with no supports and should fit together nicely without too much trouble. The case mounts to the back of the MK3S frame in existing threaded mounting holes and the extra screws provided with the printer can be used. It is a bit of a pain to get the screws in place and tightened down, but there weren't great options in terms of existing hole locations. 

The design was laid out to fit [this buck converter](https://www.amazon.com/gp/product/B079N9BFZC/), but use it or any other converter at your own risk. I take no responsibility for damage to, or problems with, your Raspberry Pi, 3d printer, or anything else as a result of your modification of things. If you're not comfortable with going that route the case will work great with a USB cable and power brick.

Compact and easy to print spool roller/holder for the Prusa MK3S. Uses 4 608 skateboard bearings to provide a smooth rolling with consistent tension on the filament unlike the standard center bar holder which sticks & slides.

Quick and easy filament roll changes. Can handle all roll sizes. Sits compactly on top of the printer frame. 

Prints in place without supports. PETG recommended.

Similar to tools that can be bought online for $15-$30 this simple 2-part print can be used to balance the standard Honda mulching mower blades when sharpening them. The two seats should match the holes in the center of the blades. If you have a different blade size feel free to comment with the size and I'll try and get it added, the more blades supported the better.

You can find videos on YouTube about how to use this type of sharpener, e.g. this one, note not my video.

Lawnmower Blade Balancer

I wanted to create a massive fidget spinner, that was on the edge of what could be done and still held between the thumb and pointer finger. This is the result. It weighs in around 190g, 6.7oz or about 0.4lbs.

Heavy enough to hurt or break fragile things if you tried so don't get carried away.

Requires:

- (3) 3/4"-10 nuts
- (1) 608 free spinning "skateboard" bearing

Printing:

Printed with 0.20 layer height, 3 perimeters using PETG.

Assembly:

- Slide the 608 bearing into the center hold aligning it with the print's edges
- Nuts can be threaded on to the bolts and fit may be fairly tight. If so apply moderate even pressure to avoid snapping the print.
