Weirhauch HW110 twin mag holder.

thingiverse

This is a TPU Magazine Holder, designed to fit over the barrel and feature an arch that securely attaches to the air cylinder for added stability. The magazines are engineered to insert only one way around, allowing for two magazines to be carried on either side of the barrel. The initial tight fit between the magazine and its housing will gradually improve after a few insertion and removal cycles. For optimal print results, orient this design upside down with its securing legs pointing upwards, ensuring a smooth print process without the need for supports or rafts. It's possible that this design may also be compatible with the HW100. If you've successfully printed it and verified compatibility, please share your findings so I can inform the community and update this information accordingly.
