Monster Acrylic Dice Tube - Conversion

Convert new or broken Monster Acrylic tubes into Dice Holders and/or Dice Tower; We have several of these tubes from Monster - used to hold playmats; a few seem to chip or crack on the closed ends after being dropped or shoved precariously into a bookbag... instead of throwing them out, we converted a few to hold dice and use them as dice tubes/towers using these inserts.
Depending on wear/tear you will need to saw off the closed end or use a hole saw drill bit to cut out a feeder hole to drop your dice in; or fall out depending on your preference.
I'll probably rework this for standard circular acrylic tubes (2" diameter)
note:
I've had to modify the percentage scale a little depending on whether I printed them using an Afinia or a Rep2x; ymmv
I printed the two (alternating) single units at 0.30mm height taking about ~90 minutes to print... no support needed; printed 6 and slid them gently into the tube; no glue needed, friction held.
I have not printed the alternating units with the mana symbols within them yet; that's lined up for this weekend.
The tube rings are used to slide over the acrylic tube as 'grips'; careful not to snap them when sliding over the outside.
