Spool Dry Box Outlet With Filament Alarm
Description
Exit For Diy Filament Dry Box With Filament Out Alarm, I Used And Led Witch Lights Up When The Alarm Is Activated, You Could Wire The Switch Up To The Print Controller Or To A Peizo Buzzer. A Cheap Storage Box Was Used In The Pictures, I Mount The Two Supports Either Side Of The Box And Use A Threaded Rod Through All The Spools Inside. When Constantly Changing Material Type/Colour I Find A Box Holding Multiple Spools Useful. **Notes** The Ptfe Tube Should Hold In On Its Own But A Tiny Drop Of Glue May Be Required Depending On How It Prints. The Battery Holder Can Be Stuck Using A Sticky Foam Pad. When Drilling The Box Mark It Up Using Masking Tape A Be Sure To Place Some Scrap Wood As A Support, Otherwise The Box Is Likely To Crack. **Electronics** I Use A Cr2032 Battery Linked Up To A Led And The Normally Open Contacts On The Switch. Another Option Is To Replace The Led With A Piezo Buzzer. A More Complex Setup Would Involve Linking The Filament Alarms To Software Via A Micro-Conroller And Maybe A Wireless Module. Let Me Know If You Have Any Questions/Notes On This Design!
