Here is a remix of the awesome Original Series tricorder designed by Wythkyn. It was reworked to assemble easier and look closer to the original prop. The parts all connect with notches and cutouts to align everything. The black parts are smooth so you can texture with paint if you want (I don't know how to model them with the texture yet). It uses 6x2mm magnets to secure the doors and flip top. It also features a medical hand scanner that fits into the lower compartment.
Display stand and graphics (zip file) included.
Supports are needed for lid housing (4) and very minimal support is needed for side edges of lower door (24). Everything else should print support-free.
