Do you think something like this Handsfree belt will work with the Handy 1?

I’ve looked at the official Handy desk mount but it’s $60 with a 2.2 stars review
Can someone suggest any alternative or DIY solutions that preferably doesn’t require a 3d printer

The easiest solution for a standing up set up requires a 3d printer. There’s this https://www.reddit.com/r/theHandy/comments/1otlsed/hands3_setup_with_battery_pack for a seated solution there are many options including using a stanley vice. If you have a handy 2 you can do this DIY Handy Hands Free ideas? - #414 by kuroa999
