After printing cleaning off rafts and supports might be necessary if printing with PLA. This guns are optimized for lego mini figures and are not associated with Brickarms in any way. Leave a like and comment if you would like more packs in the future.Print in the highest resolution and 100% in fill with supports for best results. Sorry this pack is allele small but more packs will come soon. Thank you for your continuous support. This was a challenge that me and my friend did at school and i won. My stem teacher is chill and loves legos a lot.
