Dice tower with self loading mechanism

UPDATE! V2 now with fancy brick texture! 🎉

This self-loading dice tower can re-roll your dice by simply pressing the handle. Also works as a regular dice tower.

Printing I used regular PLA for this print. No supports are needed, except for axle-main (exclude support from pinholes, see attached .3mf -files). - axle-main.stl - This part requires supports - axle-retaining-pin.stl - Print 2 - axle-retaining-ring.stl - Print 8 - axle-short.stl - Print 6 - lever-inner.stl - lever-long-2.stl - lever-long.stl - lever-short.stl - link.stl - pin-long.stl - Print 2 - tower.stl - trap-door.stl - trap.stl - Print 2 - tray.stl

Assembly Doesn't require any hardware, all parts can be printed. This should be a somewhat easy project, but I made simple drawings of what should be done in what order. Please let me know in the comments if something needs more clarifying!

Step 1: The inside assembly Attach lever-inner to axle-main and secure it with axle-retaining-pin. Make sure all parts are oriented correctly.

Step 2: The tray Attach lever-long, lever-long-2 and lever-short to tray with 3x axle-short and secure those with 3x axle-retaining-ring. The lever-long and lever-long-2 are different parts! Make sure you don't mix them up.

Step 3: The lower trap Place trap inside the tower. You may need to bend the part a bit, but it should snap on when placed correctly.

Step 4: Attach the left side Attach the lever-long-2 to the tower with axle-short and axle-retaining-ring. Make sure to use the correct hole (see images).

Step 5: Attach the right side Attach main axle from step 1 through the holes on tower, lever-long, and link. Then secure it with axle-retaining-pin. Notice the correct orientation of lever-inner.

Step 6: Attach trap door Attach trap-door with 2x axle-short and 2x axle-retaining-ring

Step 7: Attach upper trap Attach trap like you did in step 3. Make sure that trap rests against lever-inner in a low position.

Step 8: Attach handle and rotation limiter Push 2x pin-long through lever-long-2 and lever-long and secure those with 2x axle-retaining-ring.

Step 9: Check it works Push the handle down and make sure that trap-door is moved to against trap-upper. Check that there are no extra parts.

If you like this model or have improvement suggestions, I would love to see make or comments! Happy rolling!
