3D model description

After building a Flite Test foam plane, I want to create sailplane from a balsa kit. For this kit I need some weights and because I have many euro cents, I had the idea to create a parametric box, where I can set the coin diameter, the height of the chamber(s) for the stacked coins and the number of chambers. Now, I have enough weights to start with the balsa kit.
And maybe, there is someone else, who needs some weights or maybe these boxes for another purpose, like a silver coin compartment.

You can use the Customizer or the OpenSCAD file to customize your own weights or compartments with your currency. All parameters have a detailed description.


added an option to choose which parts needed (box, lid or both)
added opening slot to remove the lid with a flathead screwdriver

Doesn't Matter


1/2 of nozzle diameter. E.g. 0.2mm layer height with 0.4mm nozzle



Step 1 Insert Coin
Insert all the coins and leave min. 2mm space at the top for the lid.

Step 2 Close the Box
Press the lid on top of the box. This is a really tight fit! So you should level the lid in parallel with the top of the box and press it down. This may take some force and I have no idea, how to remove the lid.

I like to create things to save money and time. Wherever possible, I try to use aspects of ecological design. As a full-time software developer and pragmatic solution designer my focus is on the creation of customizable things.
