About this 3D model
I was using a crudely constructed PVC pipe mount to hold my extra case feeder shell plates, that sometimes caused the plates to fall. This design prevents it and I added enough surface area so you can use either double sided tape strips or Command hanger strips ( https://www.amazon.com/dp/B01N0X6SA5/ref=cm_sw_em_r_mt_dp_U_AL9wDb3FZQ6RB ) to mount it on the wall. Printed with 20% infill, 2x wall line count. You will need a 300mm print bed. Print Cost is about $3.80.
