Exhibit 99.3 

Dear [Customer]

I have exciting news to share with you about the future of Shapeways!

Earlier today, we announced a business combination agreement with Galileo Acquisition Corp. (NYSE: GLEO), a publicly traded special purpose acquisition company (SPAC). We are on track to close the transaction in Q3 2021, at which point Shapeways expects to continue trading on the NYSE under the ticker symbol ‘SHPW’.

Following this transaction, Shapeways will be even better positioned to serve as your Digital Manufacturing services platform of choice. We’ll be steadily expanding our catalog of materials and our ensemble of manufacturing and 3D printing solutions to support your ever-evolving needs. Joining the public markets is the logical next step for our company, as this new source of capital will provide greater financial flexibility with which to pursue our expansion plans and grow our market leadership.

I want you to know that we are committed to remaining the digital manufacturing partner you can trust. We can assure you that there will be no impact on our relationship – it will be business as usual. We will continue to operate as Shapeways always has, with the same end-to-end digital manufacturing services, responsive customer support and top-quality production that you have come to rely on and expect from us.

Thank you for the continued opportunity to serve you. We are embarking on a new chapter in Shapeways’ story, and are confident that our new structure will continue to best serve your needs now and into the future.

Best,

[Fname Lname]
