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.

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. […] [ ... vidi ceo članak ... ]
