A simple tool to extract Prusa CORE One nylon rivets. These are reusable rivets that are made of two parts, the outer sleeve and the inner pin. This tool extracts the inner pin which makes it possible to remove the outer sleeve from the panel hole.

To use, glide the sharp edge ender the pin head and keep pushing the tool forwared until the pin is removed.

I printed using standard 0.4mm nozzle and 0.2mm layer height.

NOTE: These reuseable rivets are known on Aliexpress and other sites as R3045.

Change log:

• July 28th 2025 - Made the vertical handle wider and easier to hold.
• Aug 2nd 2025 - Tweaked the dimension and made the Onshape model parameteric.
• Aug 4th 2025 - Made the edge slightly wide. It's useful for the second step of removing the rivet's hollow sleeve.
