About this 3D model
My version of a in spool desiccant holder. This uses threads and a cover plate to hold the desiccant in the holder while clamping onto the spool. The dimension, in mm, are the external diameter of the body and the width of spool it works best for. The top plate will adjust +2-5mm in spool width. Best to be printed from ABS/ASA so dehydrating will not affect the holder. If you have a spool size that is not available, comment and I will see if I can make a custom.
