You can make "Adderini Pistol" yourself and at your own risk.
This toy is a lot of fun, but it can be dangerous. When not in use, always keep it under lock and key away from children. Do not shoot living beings, use an archery mat/backstop!
It took a lot of work, money, time and thought to prepare this complete project, so it will not be released for free. Sorry.
You can download STL files for a relatively small fee. It will allow me to further develop and work on new projects.
Please be advised that part of the price is charged by Cults for maintenance, banking costs and VAT.
