# 2459195
€ 75.00 Price excl. German VAT tax (19%): € 63.03- UFC-Case for filter sliders with mounted filter
- Storage box with hinged lid holds all UFC filter sliders
- By popular request, we have published not only the simplified print data of the UFC case, but also the data set with a screw connection as hinge (for DIN 912 M4x10 screws). The Baader UFC case can now be ordered or is available free of charge as a 3d printable file. This can only be assembled with a little more mechanical skill, as you have to cut an M4 or M6 thread on the underside of the case in each case. You will also need the appropriate screws, which you can normally buy at a DIY store. We do not deliver screws matching the print data ourselves and ask for your understanding.
