This is a belt pouch for the Kestrel 5700 ballistic calculator. Only for print in TPU as it is designed to have a slight drag. Kestrel is to be inserted head down as shown in pics. I added a bit of the loop part of Velcro on the sides of the Kestrel near its top to add a bit more resistance removing since the top is a tad thinner. You could probably print at 98 or 99% using TPU and be good but current print is workable.
