Regretfully Just Add Sharks Ltd has closed at the end of September 2017. Over the last year Just Add Sharks Ltd has faced challenges with the vanillabox crowdfunded Open Source laser cutter project and with leads times from their suppliers. Demand for low cost laser cutters has outstriped the supply. Lack of timely supply causes delays and disappointments to customers. This is further exasperated by the drop and fluctuating value of pounds sterling. Just Add Sharks Ltd will honour all customers manufacturers warranties.

Customers should continue to email their requests for technical support, software support, spare parts and warranty enquiries to or using the contact form below.
