Found them to be a little fragile and one broke but they were a quick print!
Great design, fit perfect on my watch box!
Thanks for your feedback... usually they should be fine strength wise as long as you increase your infill and maybe add one extra shell... filament can also make a difference. Mine is still going strong after over a years use...
All the best
Yeah I do not think the model needs to change, increasing the shell would fix it. I think mostly it was on the material I used. I'll be trying wood soon I'll let you know how that goes.
