Traffic (street) signs (3D print)

Скраћена веза: https://pedja.supurovic.net/veza/9778

These are 3D models of various shaped traffic signs i did for my son.

Poles are separate from sign tables for easier printing. Once printed sign snaps on to pole. You may glue it but it is not necessary.

Sign height including pole is about 65 mm.

Intention is to print sign stickers on paper in color and glue them to the sign tables.

You can get models and more details from https://www.thingiverse.com/thing:4394933.

Knob with knurled surface for CNC 3018 X and Y axis (3D print)

Скраћена веза: https://pedja.supurovic.net/veza/9763

I stumbled upon model for bolt and nut with knurled interface https://www.thingiverse.com/thing:9095. I liked how it looks so I decided to adjust nut model and make it to become hand wheels knob for my CNC 3018 X and Z axis. It turned out pretty good.

Knob radius is 24 mm and thickness is 10 mm. It is meant to be used on 8 mm lead screw so it has 8.1 mm hole which is big enough that knob tightly sits on leading screw so it can easily turn leading screw.

There are holes for 3 mm screws if there is need to additionally secure knob on the lead screw.

DS212/DSO212/DSO202 Oscilloscope Mini Stand 3D print

Скраћена веза: https://pedja.supurovic.net/veza/9756

I needed stand for my DS212 oscilloscope. All I could find were too bulky, so I decided to design one. I posted it at https://www.thingiverse.com/thing:4347186

It is very small stand for DS212, DS02 or similar size oscilloscope or some other device. Part dimensions are 35 x 5 x 10 mm so it easy fits in any box or bag you use to carry osciloscope around.

Although You may use single stand it is more stable and practical to use two of them. Stand is tight enough to keep attached on device even if you lift it up.

Display is kept at 45 degree toward device user which is comfortable.

Fixing Baofeng UV-B5 broken battery latch using 3D printer

Скраћена веза: https://pedja.supurovic.net/veza/9740

I’ve got UV-B5 years ago. It survived lots of use and still served fine. There was one glitch – in some moment latch that keeps battery locked was broken. Radio was still usable but it happens from time to time that battery slips out of socket and radio silently turns off. It was quite annoying but hardly fixable issue.

Until today.

As I recently got myself 3D printer (Prusa I3 MK3S) I get to an idea to model and print replacement part. As every experienced computer expert, I first looked if someone else already did that. And indeed, Thingverse member Olex had the same issue and already did modeling. […]

36V CNC Spindle Motor Driver

Скраћена веза: https://pedja.supurovic.net/veza/9675

Hobby CNC machines are usually based on Arduino/Woodpecker CNC controllers with cheap motor drivers and 775 spindle motors. Motors are specified to run on 36V but CNC machines usually run it on 24V. That means motors run on slower speed than what they can do. Some controllers are able to run 36V but 24V power supplied are delivered with them. Newer Woodpecker CNC controllers are specified to run on 24V only.

Some specifications claim that 775 motor used for spindle runs at 3000-6000 rpm when powered at 24V and gets up to 9000 when powered at 36V. I wanted to run spindle at maximum possible speed for better milling results. […]
