Ugradnja konektora za punjenje baterije u Monster Truck igračku

Skraćena veza: https://pedja.supurovic.net/veza/10210

Da mi je neko pričao da ću pod stare dane da se bavim prepravkama autića na daljinsko upravljanje, ne bih mu baš verovao. Jakša je nedavno dobio jedan takav Monster Truck. Kineska proizvodnja, naravno, pa je baterija prilično loša. Hajde što mora svako malo da se puni, nego se baterija mora izvaditi iz autića, priključiti na punjač da se napuni pa onda vratiti nazad. Na sve to poklopac baterija ima zavrtanj, a paket baterija se spaja preko konektora koji nije baš lako odspojiti. Prilično smorno, složićete se.

RC Monster Truck priključen na punjač

Pošto je ceo posao punjenja baterija spao na mene, to se bacih u razmišljanje kako da tu muku skinem s grbače. […]

3D Print: Circle cutter adapter for Dremel/Proxxon router/grinder

Skraćena veza: https://pedja.supurovic.net/veza/10091

I needed to cut holes for speakers but also to carve notch for speaker edge to fit in. As I did not have proper tool for that job I had to make it on my own. As I already had cutting guide adapter for my Proxxon grinder I decided to make an adapter for it using 3D printer. It was actually adapter for Dremel tool with customization to fit Proxxon, so new tool may be used with both Proxxon and Dremel grinders.

I did modeling in FreeCAD and printed it on my Prusa MK3S 3D printer. It did a job surprisingly well. […]

Skraćena veza: https://pedja.supurovic.net/veza/10053

This is customizable zip tie holder for mounting of pictures or electronic devices at poles or similar objects. It uses mounting hole at the back of object meant to be hanged on nail or screw onto the wall.

I needed way to mount temperature and humidity meter on LACKE housing for my 3D printer. I did not want to drill holes so I got an idea to use zip ties. I needed adapter. So here is the model.

It is done in OpenSCAD and made customizable so you can easily adapt it for any zip tie size and also any mounting hole size. […]

3D model: Universal Mounting Mask for LCD Modules

Skraćena veza: https://pedja.supurovic.net/veza/10032

This is OpenSCAD customizer that allows creating universal mounting masks for LCD modules. It is suitable for the most popular LCD display modules used in hobby electronics.

There are number of parameters that may be set. However, most of them are set by default to appropriate values. Usually you just need to set dimensions of LCD module.

By default, customizer creates not only mask but also models for mounting plate with matching hole for the mask, simplified model of LCD module and protective glass insert. These can be handy while while setting mask parameters in Customizer.

You can turn of rendering of unnecessary models. […]

3D model Aluminum profile 15180×300 (for CNC 3018)

Skraćena veza: https://pedja.supurovic.net/veza/10014

I needed 3D model of aluminum profile 15180 used for CNC 3018. As I could not find it, I had to make model myself. Dimensions: 15 x 180 x 300 mm.

It is based on this drawing:

I made it available for others, if they need it.

Simplified CNC Milling Calculator

Skraćena veza: https://pedja.supurovic.net/veza/9871

Deciding what milling parameters to use can be tricky task, especially for less experienced people like me. Most of the information regarding CNC milling are related to professional equipment and may be quite detailed, hard to follow and not quite applicable to hobby machines. When you use small hobby machine, you are usually on your own. While investigated this I gathered some info that may be useful for others too, so I am sharing it.

The most simple way to deal with setting milling parameters is targeting optimal chip load. Chips are particles of material that milling tool cuts from the body of the material. […]
