Your checkouts are tracked in the member portal. Sign in and open Tool Checkouts, then My Checkouts, to see what you are checked out on. Approvers and Resource Managers see the full list under Checkout Roster.
Remove all cutoffs, partially cut material, and scrap from the makerspace immediately after your project is completed.
If you want to store partially consumed sheet stock, you may keep this only in your (sealed) rental bin. Otherwise this shop is carry-in, carry-out.
Clean up after yourself. If you leave a mess, used fluids or parts behind, you will be subject to a cleanup fee, and may have your tool checkouts revoked. Repeated offenses may result in your membership being terminated.
