I recreate Seg10 and at a battery holder for 3 x LR44 / PR44 / SR44 / LR1154 / PR1154 / SR1154 / AG13 / SG13
I printed it with support. And the inner support was difficult to remove. Therefore now the version Seg10_PR-44_Holder_Only which should be able to be printed horizontally with support.
I have added a holder for a PC Speaker (12mm diameter) and holes for better removal of the batteries.
